PSD module
C10443 series
Integrates a PSD for precision photometry
with low-noise amp in a compact case
PSD modules contain a high-precision two-dimensional PSD (position sensitive detector) and a low-noise amplifier, and are able
to perform accurate distance measurement. Using a PSD module with a dedicated signal processing unit (C10460) allows ob-
taining distance information easily.

*3: Reference value. Values may vary depending on operating environment. Position detection error is specified within a circular range
of 80% from the center of the active area to the edge. Recommended light spot size: φ0.2 mm or more
*4: Reference value. Values may vary depending on operating environment. Σ is the sum of each output voltage and calculated as
follows. Σ = VX1 + VX2 + VY1 + VY2
