For spectroradiometric analysis of LEDs, lamps, flat panel displays, solar radiation and other radiant sources, Ocean Optics Inc. has released the Jaz-ULM-200. Jaz is a family of stackable components that share common electronics and communications and are configurable for various applications. Included is a CCD array spectrometer and a microprocessor with an onboard display. Users can capture, process and store full spectra without a PC. The irradiance measurement software, stored on an SD card, collects full spectral irradiance information from the selected light source, and the data is postprocessed to yield intensity parameters, including W/cm2, lumens, lux and photosynthetically active radiation. An included Ethernet module stores data and enables users to connect to the Jaz unit via the Internet for remote measurements. A rechargeable lithium-ion battery module provides portability, and a mounting fixture enables orienting the Jaz stack horizontally for hands-free operation.
