NiSi Filter Pro Nano AIR UV 105mm

NiSi Filter Pro Nano AIR UV 105mm – 99.9% Transmission and UV Protection

The NiSi Pro Nano AIR UV 105mm filter combines high optical transmission with UV blocking to protect your lens while preserving image quality. Designed with NiSi’s ULRC (Ultra Low Reflective Coating), this filter keeps light transmission extremely high and reflectivity very low, so your shots remain clear and true to the lens’ performance.

Optical performance and image integrity

The Air UV filter delivers a peak transmission of 99.9%, which preserves the natural light reaching your sensor. In addition, it records an average transmission of 99.6% across the 420–680nm range, keeping color reproduction consistent through the visible spectrum. With reflectivity reduced to just 0.1%, the filter minimizes glare and unwanted reflections that can affect contrast and clarity.

Moreover, the filter is engineered to support cameras and lenses that exceed 100 megapixels. As a result, it maintains exceptional resolution and fine detail for high-resolution landscape, portrait, and commercial photography.

Advanced coating and durability

The NiSi Air UV uses a 48-layer ULRC nano-coating. This multi-layer coating offers scratch resistance and stain resistance. It also provides waterproof and oil-proof properties, so the filter withstands common environmental hazards encountered during outdoor shoots.

Thanks to this coating, you get both optical protection and easier maintenance under demanding conditions.

UV blocking and lens protection

The filter blocks ultraviolet light below 395nm. By reducing UV-induced interference, it helps limit blue haze and improves clarity in bright, high-altitude, or seaside shooting conditions. At the same time, the filter protects your front element from dust, scratches, and moisture without compromising the lens’ imaging potential.

Materials and mechanical design

The NiSi Pro Nano AIR UV is made from premium, carefully selected lens-grade optical glass to ensure the best possible transmission and image integrity. NiSi pairs this glass with an ultra-thin brass frame that resists deformation better than typical aluminum frames. The slim design reduces the risk of vignetting, even when used on ultra-wide-angle lenses.

The frame features precise knurling to make mounting and removal easy and reliable. These mechanical choices combine durability with a low profile to suit a wide range of lenses.

Quality control and testing

NiSi performs strict quality inspections on every Air UV filter. Each unit undergoes spectrophotometer testing to verify transmission and reflectivity. Specifically, testing includes measurement with a Shimadzu spectrophotometer, ensuring consistent optical precision across production units.

Who it’s for

Photographers who need reliable lens protection without sacrificing image clarity will find this filter suitable. It is particularly useful for landscape, travel, and outdoor photography where UV interference and environmental exposure are common concerns. Additionally, photographers using very high-resolution camera systems will benefit from its 100-megapixel compatibility.
