ALCF-A and LCF are louver films with low birefringent polycarbonate substrates. This allows them to be used in the backlight of a liquid crystal display. A common use is to prevent night reflection onto glass surfaces in automobiles. ALCF-A has a 60 degree viewing angle. ALCF-A+ is a louver film combined with a reflective polarizer (DBEF).
3M™ Infrared Reflecting Film (IRF) is a multi-layer optical film reflects > 92% of near infrared light. Color neutral, it maximizes light transmission with a natural, clear appearance. This film helps minimize thermal build-up, providing a solution for outdoor display management. Find it in ATMs, information kiosks and way-finding digital signage.
