Quadrant Photodiodes consist of an 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.

Main Features:
• Spectral range: 200-1100nm
• Small GAP
• Low dark current
• High shunt resistance
• High resolution
• Special version for 1064nm.

Series9 is the basic technology for development of multi-element arrays such as 8, 16, 32 elements. Matrix APD array for NIR detection.

Main Features:
• APD Array 32,16, 8 Elements
• QE>80% at 760-910nm
• High uniformity, low cross talk
• Temperature control device (NTC).

The HgCdTe detectors can be fabricated in quadrant arrays for tracking and positioning systems, scanning systems and night vision equipment.


The quadrant arrays require a common lead between the four elements in either the X or Y direction.
