| Planar silicon photodiodes |
Multi-channel array photodiodes consist of a number of individual element photodiodes arranged adjacently, forming a one-dimensional receiver surface on a substrate with a common cathode. These can perform simultaneous measurements of a moving beam or beams with multiple wavelengths. They are characterized by low electrical crosstalk and super-high uniformity between adjacent elements, enabling high-precision measurements. These building blocks offer a cost-effective alternative when a large number of detectors are required. The detectors are optimized for either UV, VIS, or NIR range.
They can be operated either in photoconductive mode (reverse bias) to reduce rise time, or in photovoltaic mode (without bias) for low-drift applications. A2V-16 can be coupled to any scintillator crystal to measure high-energy photons in the X-ray and gamma-ray range of the electromagnetic spectrum. Additionally, they are mechanically designed to be continuously arranged in series for applications where more than 16 elements are required.
