What types of polarizer films are available?

Mecan USA offers linear polarizer films, circular polarizer films, NIR polarizer films, wire-grid polarizer films, retardation films, sensitive color plates and polarizing glass.

How should I choose a polarizer film?

Selection depends on wavelength range, optical property, size, adhesive requirement, heat or weather resistance, transmission, extinction ratio and the intended optical layout.

What is the difference between linear and circular polarizer film?

A linear polarizer transmits light polarized in one direction. A circular polarizer combines a linear polarizer and a retardation film, and has front and back sides that must be considered in the optical system.

*1Heat / weather resistance is a five-level relative rating, not an absolute guarantee. Level 3 indicates a standard commercial resin film level.

*2Adhesive-backed polarizer films should be applied to suitable glass or cast acrylic substrates under appropriate lamination conditions to avoid optical performance issues.

*3Circular polarizer film has front and back sides. The retardation-film side and light-source direction must be checked according to the optical layout.
