Linear Photodiode Arrays

Multichannel array photodiodes consist of a number of single element photodiodes laid adjacent to each other forming a one-dimensional sensing area on a common cathode substrate. They can perform simultaneous measurements of a moving beam or beams of many wavelengths. They feature low electrical cross talk and super high uniformity between adjacent elements allowing very high precision measurements. Photodiode Arrays offer a low cost alternative when a large number of photodiodes are required. The photodiodes are optimized for either UV, visible or near IR range.

They can be either operated in photoconductive mode (reverse biased) to decrease the response time, or in photovoltaic mode (unbiased) for low drift applications. A2V-16 can be coupled to any scintillator crystal for measuring high-energy photons in the X-ray and gamma ray region of electromagnetic spectrum. In addition, the photodiode array has been mechanically designed, so that several of them can be mounted end to end to each other in applications where more than 16 elements are needed.
