3M™ ColdMirror Film(CMF)

Product Description
3M™ Cold Mirror Film (CMF) is a reflective
polarizing mirror film used in Head-up Display(HUD) type applications to provide high brightness
for the projected image while reducing infrared(IR) and visible light sources projected back to thePicture Generating Unit (PGU) through the HUD
assembly. It is a multilayer polyester-based filmwith adhesive.

Structure (not to scale)*

3M CMF
Optical Adhesive*3M DMSD considers its films and tapes as homogeneous underEuropean Union’s Directive 2011/65/EU of the European Parliamentand of the Council of 8 June 2011 on the restriction of the use of certain
hazardous substances in electrical and electronic equipment (recast)(the RoHS Recast). The product construction described above does not
represent the final homogenous film, but is a tool to assist the customer
in selecting the proper film that will suit their application needs.
