Standard Wavelengths

To preclude spectral leakage, our light meters use filter-photodetector assemblies that feature extremely high out-of-band blocking.  Following is a table of the center wavelengths for photodetectors typically available at Biospherical Instruments.   Most single wavelength detectors are 10 nm FWHM.   PAR and LuChl are broadband.  Contact BSI if you are interested in any other wavelengths
