Now available from Ocean Optics is a light-measurement system for spectroradiometric analysis of LEDs, lamps, flat panel displays and other radiant sources, as well as solar radiation. With its small footprint, powerful microprocessor and low-power display, the new Jaz-ULM-200 is a convenient, versatile alternative to standard light meters and radiometers.
Jaz is family of stackable components that share common electronics and communications and are configurable for a variety of applications. Included in the Jaz-ULM-200 stack is a CCD-array spectrometer that can be optimized for a variety of radiometric measurements and a microprocessor with onboard display.
Jaz provides functionality not found in traditional light meters, allowing users to capture, process and store full spectra without the need for a PC. With only three pushes of a button, the system’s irradiance-measurement software, which is stored on an SD card, collects full spectral irradiance information from the selected light source. This data can then be post-processed to give the intensity parameter of choice, including µW/cm2, lumens, lux, PAR (photosynthetically active radiation) or any other light intensity parameter. The system’s three-button wizard simplifies operation so that even non-spectroscopy experts are able to perform fast and accurate measurements.
The Jaz-ULM-200 includes much more than a spectrometer and microprocessor. Its Ethernet module has data storage capability via an SD card slot and allows users to connect to the Jaz unit via the Internet. The Internet capability makes remote measurements such as solar irradiance possible and enables the creation of networked sensing modules. Also included are a rechargeable lithium-ion battery module (with SD card slot) for portability and a special mounting fixture for orienting the Jaz stack horizontally to facilitate hands-free operation.
Additional system components include a direct-attach cosine corrector for collecting radiation within a 180-degree Field of View, a carrying case with shoulder strap and a rugged Pelican case for storing all your gear. Software includes the Jaz system software and JAZ-A-IRRAD, an irradiance-measurement application that comes on an SD card.
The complete Jaz-ULM-200 Light Measurement System is available for less than $6,000.
