Si photodiodes with BNC connector The S2281 series is Si photodiodes sealed in a metal package with a BNC connector. This conﬁguration allows easy connection to Hamamatsu C9329 photosensor ampliﬁer (The S2281-01 has a large terminal capacitance which may cause a gain peaking to occur when the C9329 is used with the gain set to the “M” range.). Two different spectral response characteristics are provided and the large photosensitive area makes the S2281 series well suited for optical power meters. A variant type S9219 with a visual compensation ﬁlter is also available. Hamamatsu also provides the E2573 BNC-BNC coaxial cable (length: 1 m) as an option.

Such examples include degradation of the product’s UV sensitivity and increase in dark current. This phenomenon varies depending on the irradiation level, irradiation intensity, usage time, and ambient environment and also varies depending on the product model. Before employing the product, we recommend that you check the tolerance under the ultraviolet light environment that...
