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

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.

Optically Clear Adhesive (OCA)

Optically clear adhesive (OCA) is a transparent, substrate-free adhesive layer used for bonding optical films, display parts, and transparent substrates. MCS62 and M3D49 are designed for applications where optical clarity and clean lamination are important.

  • For laminating polarizer film, waveplate film, and other functional optical films
  • Transparent adhesive layer without a PET carrier substrate
  • Roll type material; meter-length supply available.

Cold Filter / IR Cut Filter

Cold filters, also known as IR cut filters, transmit visible light while reducing infrared radiation. By lowering infrared heat load, they can help protect heat-sensitive optical components such as polarizers, optical films, and display-related parts in illumination or projection systems.

  • Dielectric multilayer coating on polished glass
  • Visible-light transmission with infrared reduction
  • Useful for projector optics, lighting systems, and 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.
