Buy Circular Polarizing Sheet

Looking for cheap circular polarizer film sheets at low wholesale prices? 3Dlens Corporation is your trusted supplier for high-quality circular polarizing film used in 3D glasses, camera filters, touch panels, and more. We ship worldwide and offer competitive bulk pricing.

Structure of Circular Polarizer Film

A circular polarizer is made by combining a linear polarizer film with a quarter wave plate retarder film. This structure converts linearly polarized light into circularly polarized light, making it ideal for applications such as circular 3D projection, CPL camera filters, and mobile photography.

Applications

Circular polarizer film sheets are widely used in:

• Circular 3D glasses and 3D projectors
• CPL camera filters and portrait photography
• Touch panels and display technology
• Optical experiments and glare reduction

All of our neutral density circular polarizer films are RoHS compliant and available for bulk orders. Circular polarization can be either right- or left-handed; learn more about handedness.
