NiSi Filter Pro Nano AIR UV 67mm

NiSi Pro Nano AIR UV 67mm – 99.9% Transmission and UV Blocking

The NiSi Pro Nano AIR UV filter in 67mm size delivers very high light transmission while protecting your lens from dust, scratches and moisture. It uses NiSi’s ULRC (Ultra Low Reflective Coating) and a multi-layer nano-coating to reduce reflectivity and limit UV interference below 395nm. This description lists the filter’s core capabilities, materials, and included accessories so you can quickly see how it fits into your kit.

Key optical performance

The filter achieves a peak transmission rate of 99.9% thanks to NiSi’s independently developed ULRC coating. In practical terms, that means the glass passes almost all visible light with minimal loss. Additionally, NiSi states an average transmission of 99.6% across the 420–680 nm range and a minimal reflectivity of 0.1%.

Because of this optical performance, the filter supports cameras and lenses that exceed 100 megapixels. In other words, it is designed to maintain very high resolution and fine detail when used on high-performance imaging systems.

UV protection and color clarity

The NiSi Air UV blocks ultraviolet light below 395nm. By filtering these UV wavelengths, the filter helps reduce UV-induced haze and blue cast that can interfere with color accuracy and clarity, especially in bright outdoor conditions.

Advanced ULRC nano-coating and durability

NiSi applies a 48-layer ULRC nano-coating to the filter glass. This multi-layer finish provides several functional properties:

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

These properties make the filter easier to clean and more resilient in demanding outdoor environments.

Premium optical glass

The filter uses carefully selected high-end lens optical glass. Each piece is subject to strict quality control to ensure consistent optical performance and image integrity when placed in front of your lens.

Ultra-thin knurling brass frame

NiSi fits the glass into an ultra-thin brass frame. The brass frame is described as more durable and more resistant to deformation than aluminum frames. The frame features precise knurling to make mounting and removal easier, and the slim profile helps prevent vignetting on ultra-wide-angle lenses.

Precision testing and quality assurance

Every NiSi Air UV filter undergoes spectrophotometer testing to verify transmission and reflectivity. NiSi uses a Shimadzu spectrophotometer during inspection to confirm the filter meets its stated optical specifications, ensuring consistent performance from unit to unit.

Available sizes

The NiSi Pro Nano AIR UV is offered in sizes ranging from 37mm to 105mm. This particular listing is for the 67mm version.

FAQ

Question: Will this 67mm NiSi Pro Nano AIR UV filter affect image sharpness on very high-resolution cameras?
Answer: The filter is specified to support cameras and lenses that exceed 100 megapixels and is designed to retain exceptional resolution and detail. NiSi tests each unit to confirm transmission and reflectivity, which helps preserve image sharpness on high-resolution systems.

Question: How does the ULRC nano-coating help in real-world shooting?
Answer: The 48-layer ULRC nano-coating reduces reflections and improves light transmission while offering scratch, stain, waterproof and oil-proof properties. In practice, that makes the filter easier to clean and more resistant to environmental contaminants, which is helpful during outdoor shoots.

Question: Will the brass frame cause vignetting on wide-angle lenses?
Answer: NiSi uses an ultra-thin brass frame to reduce the risk of vignetting, and the slim profile is intended to be compatible with ultra-wide-angle lenses. However, actual vignetting can depend on specific lens designs and focal lengths.

Question: What comes in the box and how should I clean the filter?
Answer: The package includes the NiSi Pro Nano AIR UV filter and a NiSi microfiber cleaning cloth. For cleaning, use the included cloth and standard lens-cleaning procedures; the coating’s water- and oil-proof properties make routine cleaning simpler, but always use gentle, lens-safe methods.

Question: How does NiSi verify each filter’s optical performance?
Answer: NiSi inspects each filter with a Shimadzu spectrophotometer to measure transmission and reflectivity, ensuring the product meets stated optical specifications and provides consistent results across units.
