Request InfoOptek Technology, Industrial Sensing & ControlOptek Technology Inc.'s OPR5009 SMD Optical Comparator Array is a three-channel differential photodetector hybrid array designed for high-speed, high-resolution encoder applications. Capable of a 1-MHz frequency response, each channel's open collector output switches by comparing the current levels between a pair of photodiodes on which the input light falls. A and B channels are dimensionally referenced to the Z channel for improved critical dimension control. It features internal logarithmic amplification and tightly toleranced alignment holes.See full productRelated content from Photonics MediaPRODUCTSPhotonics Spectra March 2023 IssueLidar SoftwareThe Vella line of software products from Velodyne Lidar Inc. enables users to accelerate development of lidar-based vision solutions for autonomous applications.
