PHOTODIODE
Si photodiode
S1226-18BU, S1336-18BU
For high power UV monitor, and UV to visible, precision photometry
S1226-18BU and S1336-18BU are Si photodiodes encapsulated in a TO-18 package with a UV glass window. These photodiodes have high
sensitivity from the UV to near infrared range and operate reliably when detecting high power UV radiation (such as from mercury lamps).
