Description
Hamamatsu S12742-275 Photodiode with a filter for monochromatic light (275 nm) detection
The S12742-275 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 275 nm typ. The S12742-275 can be customized to support other peak sensitivity wavelengths such as 340 nm, 560 nm.
