Polarizer Film
Polarizing Glass for 3D Projection
Heat-resistant linear and circular glass polarizers for crisp, stable 3D images
Polarizing glass is composed of a high-durability, heat-resistant polarizer such as MUHD40S laminated between optical glass substrates such as B270 or BOROFLOAT.
It is designed to withstand the intense heat of theatrical projectors and provide long service life. The precision ground finish helps reduce image distortion and supports crisp 3D projection quality.

FAQ - Polarizing Glass for 3D Projection
What is polarizing glass?
Polarizing glass is a durable optical filter made by laminating polarizer film between optical glass substrates. It is designed for better heat resistance, rigidity and optical flatness compared with film alone.
Why is precision ground finish important?
A precision ground finish helps reduce image distortion and supports crisp 3D image quality, especially in projection systems.
What is the difference between MPJ-LP200-45 and MPJ-CPR200 / CPL200?
MPJ-LP200-45 is a linear polarizing glass. MPJ-CPR200 and MPJ-CPL200 are circular polarizing glass filters that include a 1/4 retarder film for right-hand or left-hand circular polarization.
What is the difference between MPJ-CPR200 and MPJ-CPL200?
MPJ-CPR200 is the right-hand circular type, and MPJ-CPL200 is the left-hand circular type.
