NIR Dyes | Near Infrared Dyes

NIR Absorbing Materials

QCR Solutions’ Near Infrared (NIR) Dyes and laser absorbing dyes are available in a wide spectral range (700nm - 2000nm).  We have a large library of standard NIR absorbing dyes ranging from narrow notch to broad band absorbers that can attenuate selective near infrared wavelength regions.  These NIR dyes can be used singly or in combinations to create custom spectral filters for multiple applications.


Compatibility of our NIR Dyes include solvents varnishes, inks and plastic matrix. The matrix of your application will strongly influence which absorber you select.


Helpful Guide on how to calculate your absorbing dye’s starting concentration: NIR Dye | Concentration Calculation | QCR Solutions Corp .pdf.


Applications include Laser Safety Eyewear, Security, Welding Protective Eyewear, Heat Shields, Telecommunications, Digital Printing, Light Filters and more.


Below is a spectral graph (50% bandwidth) for our NIR dyes, full spectra located on TDS.

If you can not find the right absorbing dye. Just let us know your applications’ specifications and we will custom synthesize the perfect absorbing dye (UV, Vis, or NIR) for your project:


  1. Wavelengths required to be absorbed

  2. Wavelengths required for high transparency

  3. Matrix Compatibility (solvent, plastic, or other)

  4.  Process Conditions

  5. Lightfastness

  6. Thermal Stability



Let us design an absorbing dye(s) for your next NIR light filter, infrared coating or other application. Technical bulletins are available by contacting a technical representative.
