How is wire grid polarizing film different from a standard absorptive polarizer film?

A standard absorptive polarizer mainly absorbs the blocked polarization component, while a wire grid polarizer reflects it. This can reduce absorption loss and improve heat resistance in suitable optical systems.

Is this wire grid polarizer still available?

Wire grid polarizing film is currently out of stock and no longer available for order.

Is NIR polarizer film a direct replacement for wire grid polarizer film?

No. NIR polarizer film is structurally different and is not a direct one-to-one replacement for wire grid polarizer film. However, it may be a practical successor option for some near-infrared wavelength applications.

Wire Grid Polarizing Film

Film-based reflective polarizer using a metal nano-wire grid structure

Wire grid polarizing film is a reflective polarizer film that uses a fine metal nano-wire grid structure to separate polarization. It transmits one polarization component and reflects the orthogonal component.

Compared with standard absorptive polarizer films, it can reduce absorption loss and heat generation in suitable optical systems. It is used for visible to infrared applications, polarizing beam splitters, AR glass, sensors, cameras, machine vision and industrial inspection.
