| PHOTODIODE Si photodiode S2684-254 Photodiode with interference filter for monochromatic light (254 nm) detection S2684-254 uses an interference filter as its window to provide high sensitivity only to monochromatic light. The spectral response width is as narrow as 10 nm (FWHM), allowing accurate photometry without being adversely influenced by stray light. As the type No. implies, S2684-254 has a peak sensitivity wavelength at 254 nm. However, variant types are also available with different peak sensitivity wavelengths such as 340, 405, 500, 520, 560, 650 and 700 nm.
