Silicon Quadrant Position Sensitive Detectors (PSD)
Advanced Photonix's silicon quadrant position sensitive detectors provide high speed and low noise
Advanced Photonix's silicon quadrant position sensitive detectors (PSD) consist of four active areas formed in a quadrant array on a single common cathode substrate. They feature low crosstalk between adjacent elements and high uniformity in response. They are ideal for nulling, centering, or measuring small positional changes in a hermetic TO metal package.
