Near-Infrared Absorbent OPTLION®

What is Near-Infrared Absorbent OPTLION®?

The Near-Infrared Absorbent OPTLION® is an organic colorant that can absorb near-infrared rays in the 700-900 nm region.

• Pigment molecules designed by applying our colorant synthesis technology
• Can be provided as resist ink, a dispersion, a master batch, etc.
• Low additive amount, high functionality (Can be thinner than 1 µm)
• High transmittance in the visible region
  Sharp transmittance spectrum
  Absorbs 700-900 nm near-infrared light more efficiently than inorganic materials
• Newly developed colorant has higher transparency compared to conventional products

The newly developed OPTLION® has a much-improved transparency compared to the conventional version.

Uses of OPTLION®

These are some of the possible uses.

• Transmissive Wavelength Selection: Noise reduction materials, Agricultural films
• Heat Ray Absorption: Heat shield films

Transmission Spectra of OPTLION®

An example of a transmission spectrum of OPTLION® is shown below. By changing additive amounts and thickness, we are able to control the transmittance. We also have a library of products with different absorption wavelengths which we can offer according to our customers’ needs.
