Compatible for Projector Polarizer Film & Insulation Glass Lens 120x75mm RD-828(Polarizing angle 90)

120x75x1mm Projector Insulation Glass Lens HD Polarizer Film Thermal Heat Protection Polarized Yellow Screen Repair Parts for RD-828Materials: GlassSize: 120x75mm(LxW) (about 4.7x3 inches)Thickness: 1mmThat type lens suit for RD-828 RD-833That screen micro projector high-definition brightening thermal insulation glass, (also known as: polarized glass, thermal insulation film, with thermal insulation, brightening, with a brightening film on the back).Light transmission, contrast, and color have been improved accordingly.The design of polarized heat-insulating glass on the projection light path can reduce the temperature on the LCD screen by 10-15 degrees, thereby protecting the service life of the LCD screen under normal high temperatures.The silver reflective side on the surface is a brightness enhancement film, and the silver side faces the light source when installed.Package: 1PC insulation glass lens(not include other items)==========High-concerned chemical : NoneModel Number : RD-828 RD-833

• This combination film and glass component serves a dual purpose within the projector's optical path. It functions as a polarizing filter for image formation and provides a protective thermal barrier for other sensitive components.
• Manufactured to the precise dimensions of 120mm x 75mm, this part ensures a correct fit within compatible projector models. Accurate sizing is critical for maintaining proper optical alignment and effective heat management in the light engine assembly.
• A direct replacement solution for a damaged, discolored, or delaminated original polarizer assembly. Replacing this part can address image quality issues such as color shift, low contrast, or visible screen damage caused by heat exposure.
• The glass layer is designed to help dissipate heat and protect underlying LCD panels or polarizing films from high temperatures. This contributes to the longevity and stable performance of the projector's imaging system.
• This component is essential for repairing the core optical stack in LCD projectors. Installing it can restore proper light polarization and thermal protection, which are fundamental to achieving a clear, vibrant, and reliable projected image.
