Shortpass Filters (6 Total)
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.
Shortpass Filters, 800nm, 830nm and 850nm
Full visible light spectrum transmit, from 400-780nm, Tave>90%
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.
