First Sensor Single and Quadrant Photodiodes (Series Q) optimized for 1064 nm feature fast rise times, highest quantum efficiency of any silicon photodiode at 1064nm (> 35%) as well as low dark current and low capacitance making these photodiodes well suited for laser range finding, laser based target designation or any application detecting YAG lasers or similar NIR radiation sources. The components are available as single detectors, quadrant detectors or surface arrays. Quadrant photodiodes are discrete components that usually feature four optically active areas separated by a small gap. These photodiodes are used in many applications for detecting the position of laser beams, collimators and other applications to facilitate adjustment.
With a wide range of single and multi-element configurations available, First Sensor Series Q Single and Quadrant Photodiodes provide the highest quantum efficiency of any silicon photodiode at 1064nm (> 35%) as well as low dark current and low capacitance. Additionally, standard quadrant and multi-element configurations produce low cross talk (<2%). A variety of packages is available including TO metal cans, SMD ceramic packages and customized solutions.
Fast rise times make the Series Q Single and Quadrant Photodiodes well suited for laser range finding, target designation or any application detecting YAG lasers or similar NIR emitters.
