Hot mirrors are heat-reflecting mirrors that are designed to work as a shortpass edge filter by transmitting visible wavelengths at a 0° angle of incidence, while reflecting near-infrared, heat-generating wavelengths.
High Performance Shortpass Filters
These superior perfomance short-wave pass edge filters offer OD ≥4.0 rejection, high transmission in the pass band, and steep cut-off slopes.
Standard Shortpass Filters
These shortpass edge filters are made with hard dielectric filter coatings, producing a very steep transition between passband and stopband making them far superior to absorptive colored glass filters.
