What Is A Bi-Cell Detector?

A bi-cell detector is a silicon photo detector with two active photodiode areas, as compared to a quadrant detector, which has four active photodiode areas.

These detectors are able to measure extremely small changes in the position of a light beam and are used for centering, nulling and detecting and measuring position displacements.

On-Trak Photonics Inc., offers a complete line of high-quality bi-cell position sensing detectors. You can find out more about On-Trak's bi-cell detectors and other products by contacting us or checking out the resources on this website.
