Detecting Laser Beams in Collimators with Quadrant PIN Photodiodes

Quadrant photodiodes from First Sensor are discrete components that commonly feature four optically active areas divided by a small gap. These photodiodes are designed to detect the position of laser beams, in collimators and a number of other adjustment applications.

Special Features

  • Small gap areas
  • High resolution
  • Low dark current
  • High shunt resistance
  • A special version for 1064 nm is also available
