The spectral transmittance curve at each position of the cutoff linear variable filter is consistent with that of the conventional cutoff filter, and the switching wavelength of the cutoff gradually changes with the change of the spatial position on the filter. Filter variable rate is available in 22.3nm/mm and 7nm/mm. Customers can choose variable rate and spectrum fan according to their own requirements.
ECOPTIK's cut-off linear variable filters mainly covers short - wave and long - wave pass different band variable filters and can be customized.
