Quadrant PIN photodiodes (QP)

Quadrant photodiodes are discrete components that usually feature four optically active areas separated by a small gap. These photodiodes are used for detecting the position of laser beams, in collimators and many other adjustment applications.

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