The C30927 series are quadrant silicon avalanche photodiodes, useful in a variety of tracking and alignment applications.

Quadrant Detectors

Precise beam positioning can be achieved by using our quadrant PIN and avalanche photodetectors. They are designed with 4 pie-shaped quadrant sections from doping process, thus reducing to almost zero the “dead” space between each quadrant. Their structure allows high quantum efficiency and...

Excelitasâ EXACTD-362 module detects and provides highly-precise AoA information from laser range finders, laser target designators and active E.O. systems for driving effective countermeasures.

Laser Warning Detectors

Excelitas is the world leader in laser warning detectors, including the Excelitas EXACTD series for ground vehicle, naval vessels, and fixed or rotary wing aircraft Laser Warning Systems. Excelitas Silicon and InGaAs photodiodes provide detection from 220 nm to 1700 nm. These devices are offered...

Excelitas YAG quadrants are available in variable active diameters and polarity.

YAG-Enhanced Quadrant Photodiodes

Excelitas 1064 nm Long-Wavelength Si APDs

1064nm Long-Wavelength Enhanced Si APDs

The 1064nm Long-Wavelength Enhanced Si APDs (C30954EH, C30955EH, and C30956EH) are made using a double-diffused “reach-through” structure. The design of these photodiodes are such that their long wave response (i.e. >900 nm) has been enhanced without introducing any undesirable properties....
