First Sensor - Pin and Avalanche Photodiodes
We offer photodiodes in a range of technologies featuring high sensitivity, high speed, and low dark current which can be adapted to your specific requirements. Our sensors are optimized for applications where precise optical measurements are required, such as laser range finders, LIDAR systems, medical equipment, and high speed optical communications or photometry.
A photodiode is an active component that converts light into an electrical voltage (photovoltaic effect) or photocurrent. The p-n (positive-negative) junction in the silicon semiconductor serves as the physical basis for this process. When photons with sufficient energy are absorbed by the detector, this results in the formation of charge carriers (electron-hole pairs), which are separated in the depletion region and thus generate the photocurrent.
Our photodiodes are offered in ceramic and metal types and feature:
- high gain at a low bias voltage
- fast rise time with low capacitance
- high sensitivity
- laser scanners (LIDAR)
- laser range finders
- laser alignment
- analytical instruments
- precision photometry
- medical equipment
- high speed optical communications
