Wire Grid Polarizing Film

Thank you for your continued support. Due to the discontinuation of this product line by the manufacturer, Asahi Kasei Corporation, we have stopped accepting new orders for the wire grid polarizers as of April 30, 2025. We are currently handling only limited stock on a first-come, first-served basis.If you are interested in purchasing, please contact us as soon as possible, as availability is limited.

World's First Film-Based Wire Grid Polarizer ! Aluminum wire grid structure brings a high polarization separation performance in a wide range of wavelength from visible to IR (or longer) using metal nanowires. Furthermore, it has superior heat resistance compared to a general absorptive polarizer and suitable for to various applications including automotive to industrial use.

Wire Grid Polarizer

■ A reflective polarizer without absorption loss ■ Flexible & excellent processability ■ Less wavelength dependence (Visible light - infrared light)  ■ Excellent durability under high temperature (60℃/ 90%RH / 1500h, 105℃/ Dry / 1000h)

Application of Wire Grid Polarizing Film

	■ PBS (Polarizing Beam Splitter) An optical component consisting of a Wire Grid Polarizer sandwiched between prisms, widely used in AR-glass that uses LCOS.
	■ Framed filter Attachment of Wire Grid Polarizer on the glass to the frame. It can be attached to sensors and other devices.
