Phresh Photonics is a designer and manufacturer of high quality Quadrant photodetector based positioning modules
Our quadrant photodetector based positioning modules come in several standard configurations, each with a different quadrant photodetector. In addition to our quadrant photodetector modules shown here on our website, we can modify these to accommodate any quadrant photodetector you care to use. Our modules consist of a photoquadrant detector, a sophisticated, proprietary circuit that amplifies and conditions the quadrant photodetector's signal and outputs a voltage that is proportional to the movement of your beam, all housed in a convenient, easy mounting housing with a cable and standard 9-pin plug.

The outputs from our quadrant photodetector module are:
1. The combined outputs of the quadrant photodetector's two right elements (quadrants) less the combined outputs of the quadrant photodetector's two left elements (quadrants). This gives the horizontal beam position
2. The combined outputs of the quadrant photodetector's two top elements (quadrants) less the combined outputs of the quadrant photodetector's two bottom elements (quadrants). This gives the vertical beam position
3. The combined outputs of all the quadrant photodetector's quadrants . This gives the beam's relative intensity.
