HAMAMATSU 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 of S1226-18BU Silicon Photodiode :
- High UV sensitivity from the UV to near infrared range
- TO-18 package with UV glass window
- Suppressed near IR sensitivity
- Low dark current
- High reliability versus high power UV radiation
Applications of HAMAMATSU Si Photodiodes :
- Mercury lamp (λ=254nm) monitor
- Excimer laser (KrF: λ=248nm) monitor
- Other UV detection
