QCR Solutions’ Water Soluble NIR Dyes and Water Soluble Absorbing Dyes are available in a wide spectral range. We have a large library of standard Water Soluble absorbing dyes ranging from narrow notch to broad band absorbers that can attenuate selective wavelength regions. These Water Soluble Dyes can be used singly or in combinations to create custom spectral filters for multiple applications.
Our Water Soluble NIR Dyes and Water Soluble Absorbing Dyes can be incorporated into aqueous coatings, inks, and solutions. These Water Soluble 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 Water Soluble Absorbing Dyes. Also available is our helpful guide on how to calculate your absorbing dye’s starting concentration: Concentration Calculation Worksheet | 2018 | QCR Solutions Corp
