Replaceable Slit Spectrometers Offer Applications Versatility

Field-replaceable slits add flexibility to Ocean Optics spectrometers
Dunedin, FL (August 9, 2013) – Precision laser-cut slit and aperture assemblies from Ocean Optics add flexibility to the company’s QE65 Pro, Jaz, and Torus 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.

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
Dunedin, Fla., USA (July 2, 2013) – 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 synchronized hyperspectral measurements of barley and sugar beet crops to assess plant characteristics for more effective crop management.

Ocean Optics STS spectrometer collects plant data from an unmanned aerial vehicle.

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).

Dunedin, Fla. (May 7, 2013) – Ocean Optics has released the IDRaman mini handheld Raman spectrometer, a small, powerful instrument with exceptional performance for sample authentication and counterfeit detection, identification and verification. The palm-sized IDRaman mini is rugged and dependable, delivering fast, accurate Raman analyses ranging from chemical and explosive agent detection in the field to quality assurance and quality control sampling routines in the laboratory.

IDRaman mini, Ocean Optics

IDRaman mini from Ocean Optics for sample authentication and counterfeit detection, identification and verification.

The IDRaman mini overcomes many of the limitations of current handheld Raman instruments – especially size, sample measurement and power supply needs. At just 9.1 x 7.1 x 3.8 cm (3.6 x 2.8 x 1.5 in.) and weighing only 330 g (11 oz.), the IDRaman mini is not much larger than the typical mobile phone. To ensure simple and dependable operation during long field missions or manufacturing shifts where recharging is impossible, the IDRaman mini runs on two easily-replaced AA batteries.

The small size of the IDRaman mini does not limit its sample measurement performance. The unique Raster Orbital Scanning (ROS) mode scans a tightly focused beam over a wide sample area, dramatically improving the quality of the Raman measurement. ROS has benefits for liquid and solid samples, in particular solid samples that are inhomogeneous and irregularly shaped. Also, ROS is a dramatic improvement over stationary beam systems. The low average power needed eliminates sample damage and the possible ignition of explosive samples. In ROS mode, most compounds can be identified in less than nine seconds.

Featuring a bright 7.1 cm (2.8 in.) resistive touchscreen display, the IDRaman mini is easy to operate in bright sunlight and while wearing restrictive personal protection equipment. The straightforward, graphical interface is easy to navigate and allows operators of all skill levels to quickly acquire data. Sampling can be accomplished using either small vials or with a stand-off accessory for powders, residues, and solid samples.

The IDRaman mini helps make the power of Raman analysis more accessible, improving efficiency and saving on measurement costs.

Ocean Optics Unveils Novel Trade Show Display

In-line gumball sorter demonstrates remarkable range of optical sensing techniques
Dunedin, Fla. (March 19, 2013) – Ocean Optics recently unveiled what has been hailed as a clever and original trade show display – a fully functional, in-line gumball sorting machine. Debuted in February at the 2013 SPIE Photonics West Conference and Exhibition, a prestigious photonics industry event that drew 20,000 attendees to the Moscone Convention Center in San Francisco, the exhibit proved a hit. The same display will be featured at the PITTCON Conference & Expo from March 18-21, in Philadelphia, Pa., and LASER World of PHOTONICS in Munich, Germany, May 13-16.

Spectroscopy work station

Ocean Optics’ new trade show display demonstrates the versatility of spectroscopy with gumballs.

Despite its fanciful look, the Ocean Optics gumball sorter is a sophisticated optical measurement system comprising nearly a dozen spectroscopy measurement stations positioned throughout an 8-foot-tall, 6-sided structure. A series of stainless steel rails mounted to the structure delivers the gumball samples to each station, where spectrometer setups determine gumball sample characteristics such as chemical composition, color and reflectivity. Additional stations throughout the 900-square-foot booth measure absorbance and fluorescence of food coloring and flavorants, transmission characteristics of plastic containers and oxygen content in packaging. In all, nearly a dozen measurements using techniques as varied as Raman analysis, fluorescence, UV-Vis absorption and NIR spectroscopy are represented.

Each station in the gumball sorter acts as an independent analyzer: a measurement is made and the result registers the response in software, which then triggers a second device – a motorized gate – to direct the sample to the next measurement or a sorting bin. By the end of the three-day Photonics West show, more than 5,000 gumballs had been measured and sorted using spectroscopy technologies.

Ocean Optics has a long history of trade show displays distinguished by engaging presentations, live experiments and relevance to the photonics industry. And while a gumball sorter is whimsical, the science it demonstrates is serious: Every Ocean Optics instrument in the display and each technique it demonstrates can today be implemented into a process stream, used in a lab or field setting or incorporated into another sensing device.
