Phresh Photonics is a designer and manufacturer of high quality Quadrant position sensing photodiode based positioning modules
Our quadrant position sensing photodiode based positioning modules come in several standard configurations, each with a different quadrant position sensing photodiode. In addition to our quadrant position sensing photodiode modules shown here on our website, we can modify these to accommodate any quadrant position sensing photodiode you care to use. Our modules consist of a quadrant position sensing photodiode, a sophisticated, proprietary circuit that amplifies and conditions the quadrant position sensing photodiode'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 position sensing photodiode module are:
1. The combined outputs of the quadrant position sensiing photodiode's two right elements (quadrants) less the combined outputs of the quadrant position sensiing photodiode's two left elements (quadrants). This gives the horizontal beam position.
2. The combined outputs of the quadrant position sensing photodiode's two top elements (quadrants) less the combined outputs of the quadrant position sensing photodiode's two bottom elements (quadrants). This gives the vertical beam position
3. The combined outputs of all the quadrant position sensing photodiode's quadrants . This gives the beam's relative intensity.
