Tetra-Lateral PSD’s

Position Sensing Detectors (PSD)

Tetra-lateral position sensing detectors are manufactured with one single

Furthermore, typical uniformity of response for a 1 mm  spot size is ± 5%

for SC-25D and SC-50D and ± 2% for all other tetra-lateral devices.

resistive layer for both one and two dimensional measurements. They

feature a common anode and two cathodes for one dimensional position

sensing or four cathodes for two dimensional position sensing.

These detectors are best when used in applications that require

measurement over a wide spacial range. They offer high response

uniformity, low dark current, and good position linearity over 64% of the

sensing area.

A reverse bias should be applied to these detectors to achieve optimum

current linearity when large light signals are present. The circuit on the

opposite page represents a typical circuit set up for two dimensional

tetra-lateral PSDs.

For further details as well as the set up for one dimensional PSDs refer

to the “Photodiode Characteristics” section of the catalog. Note that

the maximum recommended incident power density is 10 mW / cm
