Quadrant Photodiodes
Source:
First Sensor AG
Silicon Sensor International AG Quadrant Photodiodes (Series QP) consist of a single chip with four active areas, separated by a small gap. These photodiodes are used in a wide range of applications such as position sensing of laser beams, autocollimators and other alignment applications.
Quadrant photodiode arrays from Silicon Sensor feature small gap, low dark current, high shunt resistance, and high resolution coupled with low cross talk and good uniformity. Versions optimised for 1064nm are available.
- Small Gap
- Low Dark Current
- High Shunt Resistance
- Low Cross Talk
- 1064nm Optimised versions available
- Full custom design service for customer
