Absorptive Polarizer
ProFlux® ABS series absorptive polarizers are optimized to absorb unwanted RGB light bands, reducing stray light and thermal loading caused by back reflections common in LCD projection displays. These inorganic polarizers are precision manufactured in high volumes using Moxtek’s advanced NanoStack® technology and are ideal for many applications, including: high temperature projection displays, analytical systems, automotive, medical, research, and other applications. Our wire grid polarizers are available in various sizes and shapes in both bare glass or in mounted forms.

*GCG8LGER has a protective Overcoat™ hard coating to protect the polarizer ribs. See Tech note OPT-TECH-1013 for details.
Example Optical Performance (Tested at 0°)
GCH8XCEC and SCG8XSEC are broadband absorptive polarizers designed for uniform performance across the visible spectrum at angles up to ±20°. SGG8XSEC has an absorptive layer on both sides of the wire grid structure enabling absorption of s-reflection from both directions.
Projection Display Application Design Example
Absorptive polarizers are channel specific (RGB) and designed for demanding applications that require high transmission, high contrast, and low Rs. See the example below of a 3LCD projection application:
