PHOTODIODE
Si photodiode
S2281 series Si photodiode with BNC connector S2281 series is Si photodiodes 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.). Two different spectral response characteristics are provided and the large active area makes S2281 series well suited for optical power meters. A variant type S9219 with a visual compensation filter is also available. Hamamatsu also provides E2573 BNC-BNC coaxial cable (length: 1 m) as an option.
