Product Description:

S12742-254 Band Interference Filter Silicon Photodiode For Monochromatic Light (254 nm) Detection

Features:

The Windows of the S12742-254 use interference filters and are only sensitive to monochromatic light. The spectral sensitivity characteristic width is extremely narrow at 10 nm (FWHM), so accurate photometric measurements can be made without being affected by stray light. The maximum sensitivity wavelength is typical at 254 nm. The S12742-254 can be customized to support other maximum sensitivity wavelengths, such as 340 nm, 560 nm.
