Salvo Technologies’ UV-IR filters are high-performance filters, blocking ultraviolet and near-infrared radiation from high-intensity arc lamps in illumination and projection display systems. These filters suppress UV light that can damage microdisplay panels, polymer optics, and other optical components. IR blocking reduces the heat load on these components throughout the optical train. The excellent transmission of visible light provides high brightness and neutral colors. These filters are produced with proprietary sputtered deposition technology, providing very dense filter coatings with excellent optical stability at higher operating temperatures and in varying environmental conditions.

Salvo Technologies’ Custom OEM UV-IR filters are available to match the specific angle and wavelength requirements – engineered for your specific illumination source & optics to deliver the targeted blocking. In addition to customized UR-IR filter coatings, the optics are produced to fit your application – in specific substrates, shapes, and sizes.

UV-IR Filters Features & Solutions

Salvo Technologies’ UV-IR filters protect polymer optics, microdisplay panels, and optical components from harmful UV light. They also reduce the heat load on these components by blocking IR radiation.

Salvo Technologies’ UV-IR filters provide excellent visible light transmission, resulting in high brightness. These filters also have proprietary sputtered deposition technology that provides exceptional stability at high operating temperatures and varying humidity levels.
