Photosensor modules are compact light detectors with built-in power supplies.

Photodiodes are used for the detection of optical power (UV, Visible, and IR) and for the conversion of optical power to electrical power

Fiber optic receivers are instruments that convert light into electrical signals.

Phototransistors are solid-state light detectors with internal gain that are used to provide analog or digital signals.

Optical triangulation position sensors use reflected waves to pinpoint position and displacement.

PIN diodes are three-layer semiconductor diodes consisting of an intrinsic layer separating heavily doped P and N layers.

Fluorometers measure the amount of fluorescent radiation produced by a sample exposed to monochromatic radiation.
