NiSi Filter Pro Nano AIR UV 58mm

NiSi Filter Pro Nano AIR UV 58mm – 99.9% Transmission with ULRC Nano-Coating

The NiSi Pro Nano AIR UV 58mm filter combines high optical clarity and durable protection for photographic lenses. It uses NiSi’s independently developed ULRC (Ultra Low Reflective Coating) technology to maximize light transmission while protecting the front element of your lens from everyday hazards. The filter is suitable for photographers who want to maintain image quality and safeguard gear during demanding shoots.

Key optical performance

The Air UV Filter achieves a peak transmission of 99.9% and maintains an average transmission of 99.6% across the 420–680nm range. With minimal reflectivity of just 0.1%, it minimizes glare and keeps light transmission clean and accurate. Additionally, the filter blocks ultraviolet light below 395nm to reduce UV-induced color shifts and blue haze in images.

Designed for high-resolution systems

The filter is engineered to support cameras and lenses that exceed 100 megapixels. In practice, this means the NiSi Air UV preserves resolution and fine detail when used with high-performance imaging systems, helping to retain sharpness and clarity in demanding landscape, portrait, or commercial work.

Durable multilayer ULRC nano-coating

NiSi applies a 48-layer ULRC nano-coating to the glass surface to enhance durability and resistance to contaminants. This multilayer coating provides improved scratch resistance, stain resistance, and water- and oil-repellent properties. As a result, the filter stands up better to harsh outdoor environments and frequent handling while maintaining optical performance.

• Scratch resistance
• Stain resistance
• Waterproof and oil-proof properties

Premium materials and frame design

The filter uses carefully selected high-end lens optical glass tested for consistent optical quality. It mounts in an ultra-thin brass frame that resists deformation better than aluminum while remaining lightweight and easy to handle. The precise knurling on the frame makes mounting and removal straightforward, and the slim design helps prevent vignetting even on ultra-wide-angle lenses.

• More durable and resistant to deformation compared to aluminum frames
• Easy to mount and remove thanks to a precise knurling design
• Ultra-thin to eliminate vignetting, even with ultra-wide-angle lenses

Quality control and testing

Every NiSi Air UV Filter undergoes strict quality inspection. NiSi measures transmission and reflectivity using a Shimadzu spectrophotometer to verify optical performance and consistency across production. This testing ensures each filter meets the stated specifications.

Sizes and package contents

NiSi Pro Nano AIR UV filters are available in sizes from 37mm to 105mm. The packaging for the 58mm filter includes the filter itself and a NiSi microfiber cleaning cloth.
