Quadrant PIN photodiodes are discrete components that usually feature four optically active areas separated by a small gap. First Sensor has combined the highest sensitivity, high speed, low noise, and low crosstalk into this wide range of quadrant detectors. These sensors are optimized for ultraviolet, visible, and infrared light, as well as ionizing radiation, and are used in many applications for detecting laser beam positions, collimators, and other applications to facilitate adjustment.
These quadrant Pin diodes come in three different series; Series 6 of low dark current diodes, Series 7 of fully depletable diodes, and Series Q for 1064 nm. Full customization of both the packaging and the detector is possible for each specific application.
Special Features include:
Series 6b: Blue/Green-Sensitive Photodiodes
Series 5b: High Speed Blue-Sensitive Photodiodes
Series 5t: High Speed Red-Sensitive Photodiodes
Series 5: High Speed NIR-Sensitive Photodiodes
Series 6: Photodiodes with Minimal Dark Current
Series 7: Fully Depletable IR Photodiodes
Series Q: Photodiodes For 1064 nm
