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 broadband 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.
Compatibility of our NIR Dyes includes Aqueous varnishes, inks, and plastic matrix.
