The important factors of filters include: precision of wavelength
selection, shape and width of passband, transmittance, color
matching and angle of incidence etc. Mloptic offers
following filters.
Like the hot mirrors, the cold mirrors are interference
reflectors. They allow flexibility in deciding where heat
will be removed from an optical system ........
When it is necessary to control the intensity level of
the light, these filters will attenuate a beam with very
little effect on the spectral content........
