Si photodiodes
S2281 series
Si photodiodes with BNC connector
The S2281 series is Si photodiodes sealed in a metal package with a BNC connector. This configuration allows easy connection
to Hamamatsu C9329 photosensor amplifier (The S2281-01 has a large terminal capacitance which may cause a gain peak-
ing to occur when the C9329 is used with the gain set to the “M” range.). Two different spectral response characteristics are
provided and the large photosensitive area makes the S2281 series well suited for optical power meters. A variant type S9219
with a visual compensation filter is also available. Hamamatsu also provides the E2573 BNC-BNC coaxial cable (length: 1 m)
as an option.
