NiSi Filter Pro Nano AIR UV 52mm

NiSi Pro Nano AIR UV 52mm – 99.9% Transmission and UV Protection

The NiSi Pro Nano AIR UV 52mm filter delivers high optical clarity while protecting your lens. It uses NiSi’s ULRC (Ultra Low Reflective Coating) and a 48-layer nano-coating to keep reflections low and surfaces durable. Photographers can use this filter to reduce UV interference, protect delicate front elements, and maintain image quality with high-resolution cameras.

High transmission and minimal reflectivity

The filter achieves a peak transmission rate of 99.9%, making it nearly as transparent as air. In addition, reflectivity is extremely low at 0.1%. Between 420–680nm the average transmission measures 99.6%, which helps preserve contrast and color fidelity when shooting in normal visible-light conditions.

Designed for high-resolution systems

The NiSi Pro Nano AIR UV is engineered to support cameras and lenses that exceed 100 megapixels. Therefore, you can use it with high-resolution setups without sacrificing sharpness or detail.

Advanced ULRC 48-layer nano-coating for durability

The filter incorporates a 48-layer ULRC nano-coating. This coating provides multiple protective properties, including:

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

As a result, the coating helps the filter stand up to harsh outdoor environments and everyday shooting conditions.

Blocks UV light below 395nm

The NiSi Air UV Filter blocks ultraviolet light below 395nm. By doing so, it reduces UV-induced interference such as blue haze and helps maintain color accuracy and image clarity in strong sunlight or high-altitude conditions.

Premium optical glass and strict quality control

The filter is made from carefully selected lens-grade optical glass to ensure consistent optical performance. Each unit undergoes rigorous testing with a spectrophotometer—specifically a Shimadzu spectrophotometer—to verify transmission and reflectivity values. This testing ensures that product performance matches NiSi’s stated specifications.

Ultra-thin knurling brass frame for durability and easy mounting

The frame is made of brass and designed with ultra-thin dimensions and precise knurling. This design offers several advantages:

• Greater resistance to deformation compared to typical aluminum frames
• Easy mounting and removal thanks to the knurled edge
• Ultra-thin profile that helps prevent vignetting, even with ultra-wide-angle lenses

Practical use cases

The NiSi Pro Nano AIR UV is suitable for a range of photographic applications. For example, it is a practical choice for landscape, travel, and outdoor photography where protection and optical consistency matter. It also fits portrait and commercial work that require preservation of fine image detail.
