C10443_SERIES_KPSD1027E04 Datasheet, PDF (1/4 Pages) Hamamatsu Corporation – C10443 series

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.
