NiSi Filter Pro Nano AIR UV 72mm

NiSi Filter Pro Nano AIR UV 72mm – 99.9% Transmission for Crystal Clear Protection

The NiSi Pro Nano AIR UV 72mm uses NiSi’s ULRC (Ultra Low Reflective Coating) technology to deliver extremely high light transmission while protecting your lens from everyday hazards. It combines advanced coatings, premium optical glass, and a thin brass frame to maintain image clarity and safeguard your equipment in outdoor and professional shooting conditions.

Optical performance and light transmission

The filter achieves a 99.9% peak transmission rate, making it almost as transparent as air. In addition, it shows an average transmission of 99.6% in the 420–680nm range and demonstrates minimal reflectivity of just 0.1%. These measured values ensure the filter passes light with very little loss or added reflection, helping you retain the native performance of high-quality lenses.

Furthermore, the NiSi Air UV Filter is engineered to support cameras and lenses that exceed 100 megapixels. This means you can use it for high-resolution landscape, portrait, or commercial work without compromising detail or sharpness.

Advanced ULRC nano-coating and durability

The NiSi Pro Nano AIR UV employs a 48-layer ULRC nano-coating. This multi-layer treatment provides long-term durability and surface protection. Specifically, the coating offers:

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

These protective qualities make the filter well suited for challenging outdoor environments, where moisture, oil, and abrasive particles can threaten lens surfaces.

UV blocking and image clarity

The NiSi Air UV Filter blocks ultraviolet light below 395nm. By removing UV wavelengths that can cause blue haze and other UV-induced interference, the filter helps improve color accuracy and image clarity, especially when shooting in bright daylight at long distances or at high altitudes.

Premium optical glass and quality control

The filter is made from carefully selected, high-end lens optical glass. Each piece of glass undergoes strict quality control to ensure optical performance and consistency. NiSi tests every filter with a spectrophotometer to verify transmission and reflectivity values, providing documented quality assurance for each unit.

Frame design and handling

The NiSi Air UV Filter features an ultra-thin knurling brass frame designed to balance durability and usability. Key frame benefits include:

• 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

The brass construction and knurling make filter attachment and removal straightforward while reducing the risk of cross-threading and deformation over time.

Precision testing and consistent performance

Each NiSi Air UV Filter is precision-tested with a Shimadzu spectrophotometer to confirm transmission and reflectivity. This strict inspection process ensures consistent optical performance and reliable protection for use in professional workflows.

Available sizes

NiSi Pro Nano AIR UV filters are available in sizes from 37mm to 105mm, including the 72mm size described here. You can choose the size that matches your lens thread for proper fit and performance.
