Ocean Optics Handheld Spectrometer Finalist for Prism Award

Compact IDRaman mini delivers fast, accurate Raman analyses in the field and laboratory

Ocean Optics’ IDRaman mini handheld Raman spectrometer has been selected as a finalist for the Prism Awards for Photonics Innovation. The Prism Awards honour the best new photonics products on the market and draw entries from around the world. The prestigious awards, which are co-sponsored by the trade organisation SPIE and the technology media company Photonics Media, will be awarded at the 2014 Photonics West trade show in February.

The IDRaman mini is a finalist in the Defense and Security category of the Prism Awards and is distinguished as a small-footprint, high accuracy instrument ideal for applications ranging from first responders identifying explosives to quality control specialists involved in sample authentication.

The IDRaman uses a novel sampling technique called Raster Orbital Scanning (ROS) where a tightly focused laser beam is moved or rastered across the sample in an orbital pattern. This allows an area about 10 times larger than the laser focus spot to be sampled, encountering more Raman active compounds. Because more Raman-active compounds are sampled, the resulting data incorporates a much higher sensitivity without sacrificing resolution. The increased accuracy in the Raman data further provides high confidence when identifying compounds through library matching.

Furthermore, the IDRaman mini is very small, just 9.1 x 7.1 x 3.8 cm (3.6 x 2.80 x 1.5 in.) and weighing about 11 oz. Its small size and operation from two AA batteries makes IDRaman very attractive for applications where a light, portable instrument is desired.

“The powerful performance of the IDRaman mini has captured the attention of both our customers and spectroscopy experts alike,” said Richard Pollard, President of Ocean Optics. “Combining the ROS technology into a truly handheld product makes accurate Raman measurements available for a variety of applications where fast, accurate material identification is important.”

The Prism Awards nomination follows industry recognition earlier in the year when the IDRaman mini claimed the Annual Readers’ Choice Award from Laboratory Equipment magazine.

The high signal to noise and wide dynamic range make the STS-UV useful for demanding measurements such as determining the absorbance from dilute solutions. A selection of configurations allows users to optimise optical resolution to a specific application.

Previously released versions of the STS are also available for the visible (350-800 nm) and shortwave near-IR (650-1100 nm) regions of the spectrum. All versions feature the same form factor and comparable performance specifications.

The STS-UV is anchored by a 1024-element detector in a crossed Czerny Turner optical bench. Its optical design and advanced CMOS detector elevate STS to performance levels comparable to larger and more expensive spectrometers. For example, excellent linearity, absorbance repeatability and wavelength accuracy ensure reproducibility even in large production quantities. In addition, high thermal stability performance and low baseline drift ensure that data stays accurate, even under changing environmental conditions.

The STS-UV easily integrates into other devices or can be set up next to a process line for quality control measurements or as part of a lab station. Several software control options, from drivers for LabVIEW and MATLAB to DLLs for direct control of the spectrometer in Java, Linux or Windows, allow users to seamlessly integrate STS. For laboratory experiments, all STS spectrometers are compatible with Ocean Optics’ OceanView spectroscopy software.

Replaceable Slit Spectrometers Offer Applications Versatility

Field-replaceable slits add flexibility to Ocean Optics spectrometers

Precision laser-cut slit and aperture assemblies from Ocean Optics add flexibility to the company’s Jaz, Torus and QE65 Pro miniature spectrometers. Replaceable slits give users more freedom in spectrometer design and the ability to switch easily from one application to another with the replacement of a few screws.

Replaceable Slit Spectrometers from Ocean Optics

Replaceable Slit Spectrometers from Ocean Optics

Modular spectroscopy makes possible thousands of applications by mixing and matching optical bench and other components in various configurations. The availability of field-replaceable slits in the Jaz, Torus and QE65 Pro spectrometers adds another layer of customer flexibility.

Spectroscopy is a technique in which the design criteria exist as a set of trade-offs. The optimal spectrometer depends upon the application. For some users, one of the most vexing trade-offs involves the choice of entrance aperture (slit). A larger slit increases throughput, but at the expense of optical resolution. A smaller slit yields higher optical resolution, but decreases throughput. Typically, changing the slit requires spectrometer rework that has to be performed at the manufacturer’s facility.

With replaceable slits, users can change the spectrometer’s performance directly in the field. Changing slits can be accomplished within minutes, without the need for realignment. For example, QE65 Pro users who need great sensitivity for low light applications such as fluorescence can change slits from a larger slit size to a small one, avoiding saturation in absorbance applications. Or a Torus configured to resolve closely aligned emission peaks for one application can be adjusted make low light level measurements for another application.

Ocean Optics Spectrometers Enable Field Application

STS spectrometers measure vegetation from the ground and the air

A pair of super-lightweight miniature spectrometers from Ocean Optics is helping researchers investigate plant parameters in a verdant patch of New Zealand grassland. The compact STS model spectrometers, one deployed as a ground unit and the other aboard an unmanned aerial vehicle (UAV), are making synchronised hyperspectral measurements of barley and sugar beet crops to assess plant characteristics for more effective crop management.

Ocean Optics Spectrometers Enable Field Application

Ocean Optics Spectrometers Enable Field Application

A multinational team of researchers from Germany, Italy, Spain and New Zealand developed the UAV-based system and conducted the initial experiments, gathering high-resolution reflectance spectra from the UAV at altitudes of up to 200 meters and irradiance spectra from the ground-based spectrometer. According to team leader Andreas Burkart of the Research Center Jülich IBG-2 Plant Sciences, Germany, collection of hyperspectral data by field spectroscopy is a time-consuming task and often is restricted to easily accessible areas.

The small size and weight of the STS spectrometer is ideal for use on the UAV, which allows a series of fast and reproducible measurements over any terrain, even forest or marsh. By measuring various segments across a section of the New Zealand pastureland, the system was able to assess information such as specific plots that contained live vegetation.

The STS is a remarkably small CMOS detector-based spectrometer that is less than 2 inches square (40 mm x 42 mm) and weighs a little over 2 ounces (68 g). It performs comparably to larger systems, providing full spectral analysis with low stray light, high signal to noise (>1500:1) and excellent optical resolution. For the application described here, the researchers were able to match the performance of the STS to that of a larger, more expensive commercially available field portable spectrometer, with optical resolution of ~2.5 nm (FWHM).
