Si photodiode

S12742-254

null

Photodiode with interference filter for monochromatic light (254 nm) detection

The S12742-254 uses an interference filter for its window and is sensitive only to monochromatic light. The spectral response width is extremely narrow at 10 nm (FWHM), allowing accurate photometry without any effects of stray light. The peak sensitivity wavelength is 254 nm typ. The S12742-254 can be customized to support other peak sensitivity wavelengths such as 340 nm, 560 nm, and 650 nm.
