UV Cold Mirrors, UV Filters
High transmission in UV range and visible range has been reflected to
reduce the image noise because of VIS light.
Coatings made on UV fused silica for the heat-resistance and steady
work.
680nm IR Cutoff Filter
High transmission in VIS range, and deeply blocked rate in NIR
spectrum; with single or multi-layer AR coatings, the transmission
can reach 97% or above.
Heat Blocking Filters-UV IR Cutoff Coatings
Commonly used for color cameras or other heat-blocking systems. With
UV-IR cutoff coatings on heat-resistance crystal substrate, it is
perfect as a heat blocking filter.
635nm IR Cutoff Filter
short pass filter cutting off spectrum after 635nm, to reduce the
unneeded part of red light
650nm UV-IR Cutoff Filters
High transmission in VIS range, and deep blocked rate in NIR
spectrum; with single or multi-layer AR coatings, the transmission
can reach 97% or above.
Widely used for color optical systems which only requires the visible
light to form image.
850nm Day/Night Filter or 850nm IR Filter
850nm Day Night Filter is a common filter used for day night imaging
systems, usually for CCD sensor, which is sensitive for a wide
spectrum for image forming.
