C9329_15 Datasheet, PDF (3/4 Pages) Hamamatsu Corporation – Digital output function, current-to-voltage conversion amplifier for amplifying very slight photocurrent with low noise

PHOTODIODE
Si photodiode
S2281 series
Si photodiode with BNC connector
S2281 series photodiodes are sealed in a metal package with a BNC connector and designed to connect to C9329 photosensor amplifier. Two
different spectral response ranges are provided. The large active area makes S2281 series suitable for optical power meters. A variant type
S9219 with a visual compensation filter is also available.Hamamatsu also provides E2573 BNC-BNC coaxial cable (length: 1 m) as an option.
