Position-Sensitive Detectors

These new Models 293X position-sensitive detectors (PSDs) deliver exceptional performance with a range of convenient features. With <±15-µm accuracy, and 16-bit digital output resolution, these detectors are ideal for beam position, pointing and power measurements. Unlike our quadrant- cell photoreceivers, which are ideal for centering applications, these PSDs are wellsuited for applications requiring varying beam positions or angles. Three versions with different photodetector sizes are available for varying beam sizes or beam position deviations from 4×4 mm to 12×12 mm.
