Near Infrared Dyes

NIR Dyes for Solvent Systems
Contact Us

QCR Solutions’ solvent soluble Near Infrared Dyes and Laser Absorbing Dyes are available in a wide spectral range.

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.

 

Our Near Infrared (NIR) Dyes can be incorporated into coatings, inks, solutions and plastics. These NIR absorbing dyes can be used for Laser Protection Eyewear, Light Filters (narrow or broad band), Welding Protective Eyewear, Security Inks, Graphics and many more applications. Below is a representative list of our Near Infrared Absorbing Dyes (700nm – 1000nm+). Also available is our helpful guide on how to calculate your absorbing dye’s starting concentration: Concentration Calculation Worksheet | 2018 | QCR Solutions Corp

If you can not find the right Near Infrared Dye from the above list. Just let us know your application’s specification and we will custom synthesize the perfect absorbing dye (UV, Visible, or NIR) for your project:

  • Wavelength required to be absorbed, filtered, or blocked
  • Wavelength required for high transparency
  • Matrix Compatibility (Solvent, Plastic, or other)
  • Process Conditions
  • Lightfastness
  • Thermal Stability

Let us design an absorbing dye for your next NIR light filter, Security Coating or other application. We look forward to working with you.
