Silicon Photodiodes

Custom, reliable, and highly sensitive silicon sensors and solutions for X-ray, visible and near-infrared detections.

Supplier: OSI Laser Diode Inc.


Technology type: UV and Visible Photodetectors

OSI-OE’s silicon photodiodes are silicon-based semiconductor light sensors that generate photocurrent when its active area is illuminated by light.

 This range includes tailored silicon photodiode solutions for a multitude of high-sensitivity applications. These silicon photodiodes are available as single elements, quadrants, and arrays, and are suitable for soft X-ray to visible and near-infrared.
