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.
