PSD module
C10442/C10443 series
Integrates a PSD for precision photometry with low-noise amp in a compact case
PSD modules contain a high-precision PSD (Position Sensitive Detector) and a low-noise amplifier, and are able to perform accurate distance
measurement. C10442 series uses a one-dimensional PSD, and C10443 series uses a two-dimensional PSD. Using a PSD module with a
dedicated signal processing unit (C10459 or C10460) allows obtaining distance information easily.

*3: Reference value. Values may vary depending on operating environment. C10442 series position detection error is specified
within a range of 75 % from the center of the active area to the edge, while C10443 series 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. C10442 series: Σ = VX1 + VX2. C10443 series: Σ = VX1 + VX2 + VY1 + VY2.
