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).
Features
l TO-18 package with UV glass window
l High sensitivity from the UV to near infrared range
l High reliability versus high power UV radiation
Applications
l Mercury lamp (λ=254 nm) monitor
l Excimer laser (KrF: λ=248 nm) monitor
l Other UV detection
