Data Optics Inc.
has extended its line of Jeti Specbos miniature spectroradiometers. The Specbos 1100 UV has an external pilot laser and a diffuser cap to measure luminance and illuminance, respectively, and operates from 200 to 400 nm. The 1200 model has an internal pilot laser and automatically detects the diffuser cap attachment for illuminance measurement. Model 1300 has a 50-mm-diameter integrating sphere for measuring total luminance from small point light sources such as LEDs. Spectral resolution for all models is 9 or, optionally, 5 nm FWHM; digital resolution is 4 or, optionally, 1.6 nm; viewing angle is 1.5°; luminance measuring range is from 10 to 70,000 cd/m2
and illuminance range from 10 to 100,000 lx; and luminance accuracy and reproducibility are 5% and 2%, respectively.
