Visible Opaque IR-transmitting (VOIRT) materials

Thermoplastic applications

 These products are known as near infrared cut-on filters or long wavelength band-pass filters.  They are designed to block UV and visible light while transmitting NIR light.

Epolin offers Epolight™ dye powders for addition to thermoplastic and also manufactures ready-to-mold Luminate™ compounds for your unique VOIRT application.

These applications include remote control systems, IR ports, proximity sensors, LIDAR, touch screens, machine vision and digital electronic devices.
