Introduction
4-Quadrant Photodetector QPD100, suitable for laser APT tracking systems, lidar, maritime optical communications, laser guidance, beam stabilization systems, sun tracking, and optical alignment of acousto-optic modulators, among others
1. Overview
The QPD four-quadrant position detector uses photodiodes with excellent quadrant consistency and integrates a low-noise power supply and amplification circuitry, offering features such as low noise and high gain. It is widely used in applications such as laser alignment/guidance and angle measurement.
2. Features
- Compact design
- Single-power-supply operation
3. Applications
- Spot alignment
- Angle measurement
- Laser alignment
- Displacement monitoring
