3M™ Cold Mirror Film (CMF)

3M™ Cold Mirror Film (CMF) is a polymer-based multilayer optical film with an optically clear adhesive. It is a reflective polarizer mirror film that improves polarization efficiency by transmitting one polarization state and reflecting the other, recycling light back into the system, which increases brightness over a wide viewing angle. This increase in efficiency can be used to offset battery consumption and more in LCD applications. This film is used in head-up display (HUD) applications, specifically the cold mirror, to provide high brightness for the projected image while blocking infrared (IR) and half of visible light sources projected back to the picture-generating unit (PGU) through the HUD assembly.
