FAQ - Circular Polarizer Film

Q What is the difference between linear polarizer and circular polarizer film? ▼
A Circular polarizer film combines a linear polarizer layer and a retardation layer, enabling circularly polarized light. It is commonly used in 3D optics, imaging systems and optical assemblies where polarization direction control is required.
Q What is the difference between right and left circular polarizer film? ▼
A The difference is the handedness of circular polarization. Depending on the optical system, projector, glasses or analyzer configuration, either right-hand or left-hand circular polarizer may be required.
Q What is the difference between MCPR / MCPL and CP125R / CP125L? ▼
A MCPR / MCPL is a high-contrast circular polarizer film with 140 nm retardation. CP125R / CP125L is a cost-effective circular polarizer film with 125 nm retardation, often used for polarizing 3D systems.
Q Does circular polarizer film have front and back sides? ▼
A Yes. Circular polarizer film has front and back sides because it combines a linear polarizer and a retardation layer. The correct orientation depends on the optical layout and light direction.
Q Can I buy only one sheet? ▼
A Yes. Circular polarizer film is available from a single sheet, making it suitable for evaluation, prototyping and small-volume industrial use.
