Optically Clear Adhesive (OCA) & Cold Filter / IR Cut Filter
Transparent bonding and infrared heat reduction for optical film applications
Optically clear adhesive (OCA) is used for bonding polarizing films, wave retarder films, display parts, and transparent optical components while maintaining high visual clarity.
Cold filters / IR cut filters transmit visible light while reducing infrared radiation, helping lower heat load in projector optics, illumination systems, and heat-sensitive optical assemblies.

View product
Optically clear adhesive (OCA) is a substrate-free transparent adhesive for laminating polarizer film, waveplate film, and other optical components. MCS62 and M3D49 are roll-type OCA films without a PET carrier substrate, available by the meter.
Cold Filter / IR Cut Filter
Cold filters (IR cut filters) use dielectric multilayer coating on polished glass to transmit visible light while blocking infrared heat. Useful for protecting polarizers and optical films in projector optics, lighting systems, and optical assemblies.

Technical Notes / FAQ
What is optically clear adhesive (OCA)?
OCA is a highly transparent adhesive layer used to bond optical films, display panels, and transparent substrates. Unlike ordinary adhesive tape, it is designed for optical clarity and low visual distortion.
Can OCA be used with polarizer film or waveplate film?
Yes. OCA can be used for optical film lamination. However, for precision polarization or retardation applications, final optical performance should be checked with the actual film, substrate, and bonding conditions.
What does a cold filter / IR cut filter do?
A cold filter transmits visible light while reducing infrared radiation. It can reduce heat load from a light source and help protect polarizers, optical films, or other heat-sensitive parts.
