Mar 2001Labsphere Inc., PhotonicsRequest Info
Labsphere Inc. has released the OmniLED-LTS LED life test station. One measurement sequence performs optical and electrical tests simultaneously on an array of up to 20 LEDs in <60 s. Total radiant and luminous flux, peak wavelength, dominant wavelength, and CIE purity and chromaticity are the optical measurements. Electrical measurements include forward voltage, forward current and leakage current. The station comprises a 9-in.-diameter Spectralon integrating sphere, power supplies, a CCD spectroradiometer, bar-code reader, NIST-traceable spectral flux standards and a computer.
