Si photodiode



For visible to IR, general-purpose photometry

S12915 series have high sensitivity in the visible range to near IR.
They provide higher sensitivity than the S2387 series and can be used in high-humidity environments.

- High sensitivity in visible to infrared range
- Low dark current
- High linearity
