NiSi Filter Pro Nano AIR UV 55mm

NiSi Pro Nano AIR UV 55mm – 99.9% Transmission and UV Protection

The NiSi Pro Nano AIR UV 55mm filter combines extremely high transmission with robust lens protection. It uses NiSi’s ULRC (Ultra Low Reflective Coating) and a 48-layer nano-coating to deliver near-air transparency while shielding your lens from UV light, dust, and moisture.

Optical performance and image quality

The filter achieves a peak transmission of 99.9% and an average transmission of 99.6% between 420–680 nm. It also maintains very low reflectivity at just 0.1%. As a result, the filter preserves the clarity and resolution of premium lenses and is compatible with cameras and lenses that exceed 100 megapixels, keeping fine detail and sharpness intact.

Coating, durability and environmental resistance

NiSi applies an advanced 48-layer ULRC nano-coating to the glass. This coating provides scratch resistance, stain resistance, and both waterproof and oil-proof properties. Consequently, the filter is built to withstand demanding outdoor conditions without compromising optical performance.

UV blocking and color clarity

The NiSi Air UV filter blocks UV light below 395 nm. By reducing UV-induced interference and blue haze, the filter helps maintain accurate colors and clearer images in challenging lighting situations.

Glass and frame construction

The filter uses premium, lens-grade optical glass that NiSi selects through strict quality control. It also features an ultra-thin brass frame with precise knurling. The brass construction offers greater resistance to deformation compared to aluminum frames, while the thin design minimizes the risk of vignetting on ultra-wide-angle lenses and makes the filter easy to mount and remove.

Quality inspection and testing

Every NiSi Air UV filter undergoes rigorous testing to verify transmission and reflectivity. NiSi uses a Shimadzu spectrophotometer for these measurements, ensuring each unit meets the brand’s stated optical standards.

Use cases

Use this filter to protect your front element from dust, scratches, and moisture while maintaining the full imaging potential of high-quality lenses. The combination of optical clarity, UV blocking, and environmental resistance makes it suited for landscape, travel, and outdoor photography where preservation of image detail and color accuracy is important.
