16 Sep 2024 To perform position measurements more easily, LASER COMPONENTS is pleased to offer SiTek’s small and compact position sensitive detector (PSD) modules. Either one-dimensional PSDs from 2.5mm to 20mm or two-dimensional PSDs with an edge length of 2x2mm² to 20x20mm² are integrated in a mount (PSD Holder MH01). These PSD mounts can be connected to the SEEPOS system using the DSUB9 connector and thus comprise a complete “plug & play” unit for high-precision position measurements.
The SEEPOS module is a signal processing system for one and two-dimensional PSDs. With this system, positions can be measured at a resolution of 16 bits and speeds of up to 1MHz across a large power range – from the nW to the mW range – both for DC applications and with a modulated light source.
With the software included in delivery, all parameters, such as PSD bias voltage, amplification, and the use of analog or digital filters, etc., can be set and monitored. Not only is the beam spot on the detector graphically represented in the XY direction, but the fluctuations in X-t and Y-t are shown as well. The software can also record and store data measurements for future use.
