Visible Light Sensor

Precision Micro-Optics provides two types of visible light sensors. the first type is light-dependent resistor ( LDR) whose resistance varies depending on the amount of light falling on its surface. The second type is photovoltaics device that convert light energy whether visible or infra-red light into an electrical signal.

A light-dependent resistor or photo-conductive cell is a light-controlled variable resistor. The resistance of a photoresistor decreases with increasing incident light intensity; in other words, it exhibits photoconductivity. A photoresistor can be applied in light-sensitive detector circuits, and light-activated and dark-activated switching circuits.
