AIR UV Filter (Ultra Low Reflective Coating)

The NiSi Air UV Filter is the pinnacle of optical engineering, designed for photographers who demand uncompromising clarity, precision, and protection. With cutting-edge ULRC (Ultra Low Reflective Coating) technology, this UV filter enhances the full potential of your high-quality lenses, delivering stunning, high-resolution imagery while offering robust protection against everyday hazards.

The NiSi Air UV Filter achieves an extraordinary 99.9% peak transmission rate, making it virtually as transparent as air itself. This is achieved through NiSi’s independently developed ULRC (Ultra Low Reflective Coating). The result? Minimal reflectivity of just 0.1% and an average transmission rate of 99.6% between 420-680nm. This ensures unparalleled clarity and compatibility with premium lenses, safeguarding your gear without sacrificing image quality.

Choose between two versions, with a black or silver brass frame.
