Visible Opaque Dyes

Epolight™ Visible Opaque Dyes are designed to block UV and/or visible light while allowing the transmission of all or only a portion of NIR light.  One can select a dye that allows light to begin transmitting at 500, 700, 750, 850, 950 or 1050nm.  Visible Opaque Dyes are also known as near infrared cut-on filters or long wavelength band pass filters.
