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.
