Introduction

Quadrant position sensing detectors are fabricated using a single resistive layer, suitable for both one-dimensional and two-dimensional measurements. They feature a common anode with two cathodes for 1D position sensing, or four cathodes for 2D position sensing. These detectors are best suited for applications requiring measurements over a wide spatial range. They offer high response uniformity, low dark current, and good position linearity within 64% of the active area. When strong optical signals are present, reverse bias should be applied to these detectors for optimal current linearity. The maximum recommended incident power density is 10 mW/cm². For a 1 mm spot size, the typical response uniformity is ±5% for SC-25D and SC-50D, and ±2% for all other quadrant devices.
