Si photodiode with BNC connector
The S2281 is a Si photodiode sealed in a metal package with a BNC connector. This configuration allows easy connection to Hamamatsu C9329 photosensor amplifier. The large photosensitive area makes the S2281 well suited for optical power meters. Hamamatsu also provides E2573 BNC-BNC coaxial cable (length: 1 m) as an option.
