Si photodiode
S12742-254
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
center 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.
