                          • Occasionally a customer will want a finer degree of control than provided by OmniDriver, our default production-strength device driver. Some OEM integrators don’t just want to control the spectrometer through the driver, they want to control every aspect of the driver itself.

                            For the ultimate hacker, we offer SeaBreeze, an open-source (MIT license) C/C++ device driver which lets you control every byte of data passing between your application and the spectrometer, from enumeration of the device descriptors up to the final endpoint flush. This is obviously not a trivial undertaking, and is recommended only for OEMs and K&R enthusiasts for whom the added edge in power and versatility is worth the extra investiture in time.

                            Here are some things which SeaBreeze can do, yet its beefier cousin OmniDriver would balk at:

                            • Is the driver missing a function you want? Feel free to add it.
                            • Does the driver have a bunch of bloat tied to spectrometer models you neither use nor care about? Rip it out.
                            • Want to change all API strings to Mandarin? Dive right in.
                            • Want to build on an ARM µC like Raspberry Pi, TI OMAP or Blackfin? Go ahead, we do it all the time.
                            • Want to trace every single byte exchanged at the USB level? Knock yourself out.
                            • Want to cross-compile to VxWorks or other RTOS? Should be a breeze, with existing support for GCC, LLVM, and Visual Studio built-in.
                        • Light Sources

                            • UV Sources

                            • The UV region of the spectrum is useful for the measurement of everything from small organic molecules to proteins and nucleic acids. All biological samples and many industrial and consumer products are active in the UV. Whether you are measuring absorption, fluorescence or reflectance, the UV region of the spectrum can be vital for obtaining a proper understanding of your sample. Most all UV sources also have some light emission into the visible region of the spectrum as well, making them ideal for measuring samples in both regions of the spectrum.

                              Xenon sources (PX-2 and HPX-2000 models) offer very high intensity in the UV and are useful for absorbance, fluorescence or reflectance measurements. Pulsed Xenon sources, like the PX-2, are high intensity with a lower duty cycle, making them ideal for measurements where too much UV light can damage the sample.

                              Deuterium sources (D-2000 models) are weaker but much more stable than xenon. They are ideal for kinetics or process measurements where stability over a long period of time is important.
                                • PX-2 UV Source

                                • The PX-2 Pulsed Xenon Lamp is a high flash rate, short-arc xenon lamp for the ultraviolet (UV). With an output from 220-750 nm, it is ideal for absorbance and reflection measurements. Because of the shorter duty cycle the PX-2 is also useful for fluorescence and phosphorescence measurements.

                                  The PX-2 operates at speeds up to 220 Hz, offers excellent pulse-to-pulse stability. It can be triggered by an external TTL pulse and offers software control of the flash rate.

                                  The spectrometer sampling can be altered so that a variable number of flashes are observed during each integration period. In the Single Mode of PX-2 operation, a single flash occurs during each integration period so you can easily synchronize operation of both the xenon lamp and detector. In Multiple Mode a steady, consistent light exposure is provided for each integration period ensuring reliable absorbance and reflection measurements.

                                  The PX-2 has an SMA 905 output connector and seamlessly integrates with Ocean Optics miniature fiber optic spectrometers and accessories, including optical fibers, cuvette holders, probes and other sampling optics.
                                • HPX-2000 Family UV Source

                                • High-powered, Continuous Xenon Light Sources

                                  The HPX-2000 is ideal for reflectance or florescence applications where often a strong source is required. The light has a 35 W xenon source and features an integrated filter holder to condition the light before it enters the fiber optic.

                                  The HPX-2000-HP-DUV light source is much more intense, especially in the UV region. Driven by a 75 W source, the HPX-2000-HP-DUV provides output intensity that is almost 4x higher across the entire range compared to the output of the HPX-2000.

                                  Both models have an integrated shutter that can be controlled by a a TTL signal or a switch on the front panel, allowing you to limit the exposure of the sample to this high intensity source.

All models include an easy-to-replace bulb, keeping your measurements going with fast lamp changes. The D-2000-S and D-2000-S-DUV have a shutter with TTL control to limit the exposure of samples to the UV light emitted by the source.
                              • UV-Vis-NIR Sources

                              • Whether you are studying a sample that has multiple features in different areas or you analyze a variety of different samples in your lab, a light source that covers a wide spectral range is useful. From organics and small molecules to the near-IR absorption of plastics and polymers, a combination light source allows you to extend the capabilities of your measurement. Using a combination of two lamps or a single lamp that has a wide spectral output, the entire UV-Vis-near-IR can be accessed.

                                Xenon sources are very intense in the UV and have a strong, flat profile in the visible and near-IR region. They are useful for absorbance, fluorescence or reflectance measurements. Pulsed Xenon sources, like the PX-2, are high intensity with a lower duty cycle, making them ideal for measurements where too much UV light can damage the sample.

                                A light source containing both a deuterium and tungsten or halogen lamp can also cover the UV, visible and near-IR regions of the spectrum. For applications from color measurement to industrial quality control, these sources are the most flexible available. Deuterium sources are weaker but more stable than xenon. They are ideal for kinetics or process measurements where stability over a long period of time is important.

The DH-mini enables applications that are otherwise challenging for compact light sources, such as fiber probe-based reflection measurements where throughput is a challenge. Absorption and transmission measurements with opaque or optically dense samples also benefit from the high intensity of the DH-mini.

                                    The DH-mini is packed with features that make it easy to use. The tungsten and deuterium source bulbs can be turned on and off individually, limiting stray light in challenging measurements. An internal shutter can be opened and closed using simple buttons with LED indicators on the front panel. For automated processes or remote measurements, a TTL signal also can be used to control all functions.

                                    The DH-mini has been designed with OEM integration in mind. Not only does it provide high power from a small footprint, it also makes integration a breeze with full remote control of all functions via a 4-pin TTL connector. Galvanic isolation of the TTL pulse provides reliable performance in complicated environments like an electrically noisy production floor.

                                  • Radiometric calibrated light sources are carefully measured and characterized to deliver a known quantity of light with a very low uncertainty. Whether it is for the highest level of traceability when working with regulatory agencies in food or pharmaceuticals or for new instrument design where accurate comparison as a necessity, radiometric calibrated standards deliver the data you trust.

                                    Using well-know and traceable standard materials, the light source you purchase is measured to these reference points. This creates an unbroken chain of traceability providing you with the highest quality and most reliable data.

                                    Since each component of a calibrated system carries a small amount of error or uncertainty, your particular light source has to be carefully and individually characterized. Your system is analyzed statistically and compared to well-known references and the resulting calibration data for your radiometric source is defined on a certificate that explains each contribution to uncertainty and how that influences each calibration data point.

                                    Our commitment doesn’t stop with a certificate and data. Our team of application engineers will take the time to explain the subtle nuances of radiometric calibration and help you understand why this level of detail is so important for some measurements.

                                    Our radiometric calibrated sources cover the UV to the near-IR. Let us help you find the right source for your traceable measurement needs. Radiometric calibration services are also available.

                                        • The emission lines from atomic lamps are the most reliable standards for wavelength calibration. Resulting from atomic level transitions, these emission lines are intrinsic to the source and therefore are primary standards, requiring no calibration themselves. Atomic emission is almost infinitely narrow; meaning the position of the emission line can be accurate to 0.001 nm. This high level of accuracy and reliability make these lamps ideal for procedures from routine checks of instrument performance to total recalibration of a spectrometer.

                                          Available in configurations that span the UV to the near-IR, choose a calibration source or use a combination of different sources that match with your analytical wavelengths of interest and span your entire measurement range. These calibration sources operate with either a 12 VDC power supply (included with the source) or 9V battery.

                                        • Ocean Optics’ light sources are built to last. Over time, lamps will degrade and need to be replaced. The lifetime of a lamp is impacted by both operation and the slow leakage of fill gases over an extended period of time. We offer a complete range of lamps and power supplies to ensure the usefulness of your light source for many years.

                                      • If a spectrometer is the heart of an Ocean Optics system, and its light source the lungs, then fibers and probes are the circulatory system – the conduits through which light travels to reach the extremities and bring life to the measurement of a sample.
                                          • Fibers

                                          • Optical fibers route light from one optical component to another efficiently and conveniently, eliminating the need for time-consuming alignment. We offer optical fibers off-the-shelf in a variety of core diameters and lengths, all protected by quality jacketing and terminated with SMA connectors for seamless integration with our full suite of spectrometers, light sources, and accessories.

                                            Lab-grade fibers are an economical solution for many needs, while premium-grade fibers are designed to be more robust and aesthetically pleasing.
                                              • Patch Cords

                                              • Patch cords route light from one location to another using one or more optical fibers in a single length of jacketing.

                                                Linear Keyed SMA Patch Cords
                                                Fiber assemblies with keyed SMAs connect to the spectrometer with a well-defined and repeatable orientation. Our linear keyed SMA patch cords convert a bundle of fibers at one end into a linear format at the keyed SMA end for matching to the spectrometer slit. This configuration is typically only more efficient when using a spectrometer with a tall detector, such as the QE Pro, Maya, NIRQuest, or Ventana optical benches.

                                                Infrared Fiber Patch Cords
                                                At wavelengths beyond 2100 nm, infrared fiber materials like fluoride or chalcogenide offer lower transmission through the MIR.
                                              • Bifurcated Fibers

                                              • Bifurcated fibers have two fibers side-by-side in the common end and break out into two legs at the other end. The fiber type used in each leg can be the same or different, allowing optimization of fiber core diameter or wavelength range based on the application.

                                                Bifurcated fibers are good for efficiently routing equal amounts of light from a source to two different locations, and from a single sample to two spectrometers configured for different wavelength ranges (UV/VIS and VIS/NIR).

                                                lab-grade bifLab-grade bifurcated fibers are intended for light use, with PVDF zip tube jacketing and basic hex SMA connectors. They offer high quality at an affordable price.

                                                Premium-grade bifurcated fibers meet the more demanding needs of field and industrial use, premium-grade bifurcatedand rougher handling. They are built with silicone-coated steel monocoil jacketing and high-quality knurled SMA 905 connectors, with an interior Nomex braid for superior strain relief.
                                              • Splitters

                                              • Fiber splitters are comprised of three fibers – two fiber legs on one side that overlap inside a junction with a third fiber at the common end. The fiber type used in each leg is typically the same, but can also be custom configured to have different fiber core diameters or wavelength ranges.

                                                Fiber splitters are good for mixing light from two different locations and delivering it through a single fiber to a spectrometer or sample. This ability can be used to combine illumination from two different light sources, or to mix light collected from two different sampling points before delivery to a spectrometer.

                                                These assemblies have lower transmission than bifurcated fibers due to the inefficient geometrical overlap between the fiber cores at their junction point. Split fiber assemblies for small diameter core fibers are not recommended for this reason, as their thicker cladding diameter results in minimal geometric overlap.

                                                • A probe is a compact, versatile way to measure diffuse and specular reflectance, backscatter, or fluorescence from samples as varied as solids, solutions, and powders. Reflection and backscatter measurements can provide quantitative information about the color, appearance, and chemical composition of a sample.

                                                  • Fluorescence of liquid samples
                                                • Transmission Dip Probes

                                                • Transferring a sample to a cuvette for an absorbance measurement isn’t always convenient, nor does it allow real-time monitoring of reactions and process streams. A transmission dip probe solves this problem by placing the “cuvette” at theTransmission of Solutions Measurements tip of a probe, with openings to allow solution to freely flow through during measurement.

                                                  How does it work?
                                                  In a transmission dip probe, light is transmitted from the illumination fiber through a plano-convex lens for collimation, after which it passes through the open probe tip to a flat, second-surface mirror at the tip of the probe. The light reflects from this mirror and is focused by the lens onto the read fiber within the probe ferrule. The advantage of the transmission probe is its compact optical design, which fits into a narrow stainless steel or PEEK body, or ferrule.

                                                  The trade-off with dip probes is that they measure both transmitted light and backscattered light from the sample, and have internal reflections that limit the dynamic range of the measurement. Still, they are a convenient and cost-effective option for many on-line and lab applications.
                                                • Fluorescence Probes

                                                • Probes offer a convenient alternative to measuring fluorescence in a cuvette. When immersed in a solution, they excite and detect fluorescence of the sample material closest to the tip. This enables measurements of flowing solutions, as well as samples that are highly concentrated or prone to reabsorption of emitted fluorescence. Probes are also excellent for direct measurement of solid and particulate samples.

                                                  Fluorescence in Solutions
                                                  A basic reflection or backscatter probe works very well for making fluorescence measurements in solution. A probe with a large core fiber such as the QR600-7-UV-VIS will excite and collect the most fluorescence.

                                                  For process applications, a more robust probe such as our front-surface fluorescence probe may be warranted. It requires very little penetration into the sample and is compatible with industrial fittings.

                                                  Fluorescence of Solids and Powders
                                                  Solid and powdered samples don’t lend themselves well to traditional cuvette-based spectrofluorometer measurements. A reflection probe, however, can perform excitation and detection of fluorescence when angled and placed in a probe holder at a small, repeatable distance from the sample. This allows samples to be measured in place and non-destructively.
