Si photodiode

S2281-01

null

Si photodiode with BNC connector

The S2281-01 is a Si photodiode sealed in a metal package with a BNC connector. This configuration allows easy connection to Hamamatsu C9329 photosensor amplifier (S2281-01 has a large terminal capacitance which may cause a gain peaking to occur when C9329 is used with the gain set to the "M" range.). The large photosensitive area makes the S2281-01 well suited for optical power meters. Hamamatsu also provides E2573 BNC-BNC coaxial cable (length: 1 m) as an option.


Features
- Metal package with BNC connector
- High sensitivity
- High reliability
