Description

The NCL type HECM Cold Mirror is supplied in various shapes and thicknesses. Our standard substrate is Schott Borofloat heat resistant glass. Sizes up to 13" x 13", 10" x 16" or 19" diagonal octagon are available. Sizes as small as 1.0 mm x 1.0 mm x 0.25 mm can be produced in large volume. Diameters from 1.5 mm to 18.75" can be supplied, but at a higher cost than rectangular shapes.

Environmental Resistance

NCL Cold Mirrors can withstand severe exposure to heat and ultraviolet radiation because they are made entirely of glass and stable clear oxides. Damage resistance to rain, humidity and chemicals exceeds MIL-C-675-C, which has long been used to specify shipboard optical equipment. This product is suitable for space or underwater application.
