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