What does a cold filter or IR cut filter do?

A cold filter transmits visible light while reducing infrared radiation. This can reduce heat load from a light source and help protect polarizers, optical films and other heat-sensitive components.

Optically Clear Adhesive (OCA) & Cold Filter
/ IR Cut Filter

Q: What is optically clear adhesive (OCA)?

Optically clear adhesive is a highly transparent adhesive layer used to bond optical films, display panels and transparent substrates while maintaining optical clarity.

Q: Can OCA be used with polarizer film or waveplate film?

Yes. OCA can be used for optical film lamination, including polarizer film and waveplate film. For precision polarization or retardation applications, evaluation with the actual film, substrate and bonding conditions is recommended.

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.

Technical Notes / FAQ

Q What is optically clear adhesive (OCA)? ▼

A 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.

Q Can OCA be used with polarizer film or waveplate film? ▼

A 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.

Q What does a cold filter / IR cut filter do? ▼

A 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.
