Hot Mirrors
Hot Mirrors
Hot mirrors are used to reflect the IR spectrum (heat energy), while transmitting the visible light, and blocking UV light. Typically used anywhere that visible light must be cooled. Hot mirrors are often used in conjunction wtih cold mirrors. Applications include motiion picture projectors, projection TV, endoscopes, microscopes, and exotic sun glasses.
These dichroic infrared reflectors are used to transmit the visual light 425 to 675 nm spectrum and reflect the near infrated 750 to 1150 nm. They also block most UV. Our type SHM is used in projectors, Fiber optic illuminators, stage lighting, and other applications requiring maximum protections from light damage.
CCL's SHM Hot 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
CCL Hot 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.

These dichroic visual reflectors are generally used at a 45 degree angle to deliver visible light in the 425nm - 650nm spectrum to film in a projector, and transmit the infrared energy to a heat sink. Our type of HECM is designed for use with large xenon lamps.

Dielectric Beamsplitters
Dielectric Beamsplitters
Divide transmitted and reflected images without absorption (of light) loss. Dielectric beamsplitters are superior to typical two-way mirrors, where the metal absorbs a lot of the transmitted light (brightness). Typically used for special effects. Applications include teleprompters, movie making, microscopes, heads-up displays, rifle sights, camcorders, and industrial photo processing.
