Kodenshi provides many types of photo detectors to respond to the needs of a variety of applications. Photodiodes are used where linearity in light level detection is needed and PIN Photodiodes where high efficiency and high speed response are required. Phototransistors and Photodarlingtons are best when a weak light signal is present, switching applications exist, or shen there are high output voltage requirements. Location detectors for camera auto focus applications round out our family of...
