SiTek 1LA16-2.5_SU89 PSD Array

Laser Components has introduced the SiTek 1LA16-2.5_SU89, a PSD array with 16 parallel 1-dimensional PSDs placed on the same chip. This enables simultaneous position read-out from the 16 segments and high speed 3D contour measurements with low cross talk between the segments. Each segment has the same high linearity and high speed as SiTek's standard 1-dimensional PSDs.

The PSD array has SiTek's built-in stray light elimination, a patented design that eliminates the decrease in speed and linearity due to stray light. The PSD array can be used together with either a line laser or multiple laser beams.
