Photodiodes are solid state light detectors that, when illuminated, generate an output which is proportional to light level. A photodiode consists of a shallow diffused P-N junction with accessible connections. Photodiodes offer unity gain, which can be a limitation in some applications.

We offer industry standard products as well as parts designed for optimum response through the visible part of the spectrum (blue enhanced), and variants designed with low junction capacitance for fast response.

ESPROS offers high-sensitivity, high-speed, low-cost photodiodes particularly suited to light-barriers, light-curtains, health monitoring and other similar applications.
