Request InfoGL OpticFAIRPORT, N.Y., Jan. 5, 2016 — The GL OptiLight LED 127 CLC programmable light source from GL Optic is used to calibrate front and back cellphone and digital camera sensors. Internal LEDs are controlled through an automated, multilevel calibration procedure without the need for an external measurement device. Two identical, selectable color temperature sources are provided, with several levels of radiance for simultaneous calibration. Replicating light sources like D50, D65, D75, A or TL 84, the light source can be used as a precise calibration reference for many types of optical instruments in manufacturing...See full productRelated content from Photonics MediaPRODUCTSPhotonics Spectra December 2023 IssueConstant Voltage LED DriversThe GP-CVP075P-xxVH-T02 Series from GlacialPower are constant voltage LED drivers that have an AC phase-cut dimming feature.
