Request InfoOptronic Laboratories LLCThe OL 700-4pi integrating sphere from Optronic Laboratories Inc. is designed for total and partial luminous flux measurements of LEDs and on-site calibration. An internal reflectance/auxiliary lamp calibrates the sphere and compensates for changes in the spectral efficiency caused by the self-absorption and reflectance properties of the LEDs and their packages. For use with the OL 770-LED test and measurement system, the 9.75-in. high-reflectance integrating sphere has a 90° entrance port to exit port configuration, standard viewing angle positions of 40°, 60°, 90° and 120°, and >99%...See full productRelated content from Photonics MediaPRODUCTSPhotonics Spectra December 2023 IssueLED Photoreactor ModuleThe PHOTOCHIP high-power LED photoreactor module from Uniqsis Ltd. provides chemists with a benchmark tool to run photochemical reactions with efficient mixing and controlled temperature.
