What are photodiodes, and how do they work?

What exactly are photodiodes? A photodiode is a photodetector element, which means an optical sensor that can convert an optical signal into an electrical signal. Our high-sensitivity, low dark current PN photodiodes are ideal for high-speed applications.
The silicon photodiode array is an optical sensor made up of several photodiodes arranged in a single package. It can be used in awide range of applications such as position detection, imaging, and spectrophotometry.
These elements can be applied in various sectors, including industry and aerospace; in particular, photodiodes are the flagship products among Optoi optical components for the Group’s long-standing Industrial division.
