Description
Hamamatsu S2281 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 C9329-01 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.
Features
– Metal package with BNC connector
– High sensitivity
– High reliability
