New Optical Sensing Device from Ocean Optics Simplifies Multi-point Sampling

The Jaz brings harmony to applications where multi-channel spectral analysis is necessary
Dunedin, Florida (June 18, 2008) – Now available from Ocean Optics is a modular optical sensing platform that easily integrates multi-point spectral sampling and reference monitoring into process streams and other sample environments.

Jaz is a family of stackable, modular and autonomous components that share common electronics and communications. At its heart is a miniature CCD-array spectrometer, available with user-selected grating and slit options optimized for a variety of application needs, in a design that accommodates up to 8 spectrometer channels.

Each Jaz stack includes a powerful microprocessor and display, so that full spectra data can be acquired, processed and stored onboard the unit — without the need for a PC. Spectral data also can be transferred to a laptop or desktop PC for additional post-acquisition processing, such as displaying x-axis values in wavenumbers or nanometers or combining data from multiple spectrometer channels in a single graph.

“Smaller, lower-cost optical sensing systems like Jaz make feasible some spectral applications that were previously cost-prohibitive,” says Mike Kayat, Ocean Optics Vice President of Sales & Marketing. “For example, instead of using expensive laboratory spectrophotometers to monitor the chemical composition of a finished product, a series of less expensive Jaz modules can be installed into process lines or used as rugged handheld instruments in the field.”

In addition, Jaz systems can be rapidly configured for a variety of absorbance, reflectance and emission measurements, with potential applications as far-ranging as monitoring of dye baths for carpeting, verification of color and appearance of food, and analysis of chemical dissolution processes for pharmaceuticals production.

Jaz is also available with an Ethernet module that allows users to connect to the Jaz unit via the Internet, making remote measurements possible and enabling the creation of networked sensing modules. The Ethernet module also has data storage capability via an SD card slot.

The Jaz Lithium-Ion battery module is rechargeable in the field via a solar cell, or in the QC lab or process stream using the Power over Ethernet connection (100 Mbps, IEEE 802.3-compliant 10/100 single-cable), the USB 2.0 port or an external power supply. The battery module also has a power-conserving sleep mode for long-term measurements and two additional SD card slots for storing data. Additional Jaz modules include VIS/NIR or LED light sources.

Jaz can be connected to a variety of fiber optic sampling accessories, including process-ready optical multiplexers, transmission dip probes and flow cells, and temperature-regulated cuvette holders. An add-on holster accessory makes the Jaz wearable, freeing hands to manipulate sampling devices.
