Anti-Reflective Filter

AR filters are used to reduce glare and reflection. They improve the brightness of transmitted images or light beams to reach the final target of a minimum loss at visible wavelength. Kupo provides its AR filters by different manufacturing approaches, vacuum evaporation & Sol-Gel dipping, for the best use of your specific applicationsˇG
(1) Vacuum EvaporationˇG
Anti-Reflective Filter-1
