Each of Phresh Photonics' Quadrant Photodiode Positioning Modules is a complete module that combines a Silicon Quadrant Photodiode (4-element array) with the necessary amplifiers and position sensing circuitry needed to accurately sense and read the position of, or the movement of, a light beam on the sensing area .
Quadrant Photodiodes produce a current that is proportional to the light falling on it. This current is converted and amplified to a useable voltage. The resulting voltages are then summed and divided by this module to provide X, Y and Sum outputs

Phresh Photonics offers several different versions of our Quadrant Photodiode Module
Each quadrant photodiode module provides an accurate amplified output of the sum and difference currents of the detector, all in a convenient, rugged housing with an easy to connect cable.
Our quadrant photodiode modules are an excellent solution to your beam positioning and locating challenges.
Our quadrant photodiode modules are as easy to use as plug and play
Our standard quadrant photodiode modules are listed below.
Additionally, we can customize any existing quadrant photodiode module, or develop one for your unique application
