Reflective Cover
VRC1-PC380
Product Description
3M VRC1-PC380 is a multi-layer reflective polarizing
mirror film laminated to a polycarbonate substrate for use
in automotive head up display systems. In these systems,
through polarizing mirror functionality, one polarization
state is transmitted while the other polarization state isreflected. By reflecting away half of the visible ambient
light, the temperature can be reduced in the head up
display system.

Construction/Performance
Multilayer structure with polycarbonate (PC), adhesive,multi-layer optical film and polyethylene (PE) andpolyethylene terephthalate (PET) protective films.

MethodEffective Transmission

Sample: 76.2 mm x 127 mm (3" x 5") 0 degree, bias
Light source: Fostec-DCR II DC regulated lightsource Equipment L Spectra Colorimeter, Model
PR-650 SpectraScan – Photo Research, Inc.,
Polarizer assembly
Procedure: Measure luminance with VRC sample on
the illuminated Teflon box in correct orientation
Effective Transmission is given by following
equation: ET= Ld/Ln
Ln: Luminance at normal axis of polarizer
Ld: Luminance with VRC between backlight andpolarizer

Color change (∆E*)

3M TM-019, ASTM E 1164
Light Source: D65/10
Measurement: transmission
Size: 76.2 mm x 127 mm (3" x 5") 0 deg. Bias
Equipment: BYK Color Sphere(equivalent to Minolta Co., Ltd., Spectrophotometers
CM-3700)
Procedure:
Measure color (L*, a*, b*) of transmitted light throughVRC before and after environmental testing.
Then, color change of environmental testing (∆E*) iscalculated,∆E* = √∆L*2 + ∆a*2 + ∆b*2
