NiSi Filter Pro Nano AIR UV 43mm

NiSi Pro Nano AIR UV 43mm – 99.9% Transmission for Clear, Protected Images

The NiSi Pro Nano AIR UV 43mm filter delivers extremely high light transmission while protecting your lens. It uses NiSi’s ULRC (Ultra Low Reflective Coating) to keep reflections to a minimum. As a result, the filter preserves image clarity and protects optics from dust, scratches, and moisture without compromising picture quality.

Transmission and optical performance

This filter achieves a 99.9% peak transmission rate, making it nearly as transparent as air. In practice, that means very little light loss when you attach the filter to a lens. Additionally, the filter shows an average transmission of 99.6% between 420–680nm and a minimal reflectivity figure of 0.1%. These measured values support consistent, clean imaging with premium lenses.

High-resolution compatibility

The NiSi Air UV is built to support modern, high-megapixel systems. Specifically, it is engineered to handle cameras and lenses that exceed 100 megapixels. Therefore, you can use this filter for landscape, portrait, and commercial work where retaining fine detail and sharpness is essential.

Durable ULRC nano-coating

NiSi applies an advanced 48-layer ULRC nano-coating to the glass surface. This coating improves the filter’s resistance to common problems you encounter outdoors. In particular, the coating adds:

• scratch resistance
• stain resistance
• waterproof and oil-proof properties

These properties help the filter withstand harsh shooting environments and reduce the need for frequent, aggressive cleaning.

UV blocking for improved color and clarity

The filter blocks ultraviolet light below 395nm. By filtering out these UV wavelengths, it reduces blue haze and other UV-induced color shifts. As a result, photographs often show improved color accuracy and sharper detail in challenging lighting conditions.

Premium optical glass and quality control

NiSi uses carefully selected, high-end optical glass in the Pro Nano AIR UV. Each filter piece undergoes strict quality control. In particular, NiSi tests transmission and reflectivity with a Shimadzu spectrophotometer to verify optical performance. This testing ensures consistent results across production batches.

Ultra-thin knurling brass frame

The filter’s frame is made from brass and designed to be ultra-thin. Compared with typical aluminum frames, the brass construction offers greater resistance to deformation. The precise knurling improves grip, making the filter easier to mount and remove. The slim profile also helps prevent vignetting, even on ultra-wide-angle lenses.

Available sizes

NiSi Pro Nano AIR UV filters are available in sizes from 37mm to 105mm. The 43mm model is one option within that range, allowing you to choose the correct thread size for your lens.

FAQ

Question: Will the NiSi Pro Nano AIR UV 43mm affect image sharpness or color?
Answer: No. The filter’s 99.9% peak transmission and 0.1% reflectivity preserve sharpness and minimize color shifts. It also blocks UV light below 395nm to reduce blue haze and help maintain accurate colors.

Question: Is this filter suitable for high-resolution cameras over 100 megapixels?
Answer: Yes. The NiSi Air UV is engineered to support cameras and lenses exceeding 100 megapixels while retaining fine detail and resolution.

Question: How durable is the coating and how should I maintain the filter?
Answer: The filter uses a 48-layer ULRC nano-coating that provides scratch, stain, water, and oil resistance. For regular maintenance, use the included NiSi microfiber cleaning cloth and gentle cleaning techniques to protect the coating.

Question: Will the filter cause vignetting on wide-angle lenses?
Answer: The ultra-thin brass frame is designed to minimize vignetting, even with ultra-wide-angle lenses. The slim profile reduces the chance of darkened corners compared with thicker frames.

Question: What comes in the box when I buy the 43mm model?
Answer: The package includes the NiSi Pro Nano AIR UV filter and a NiSi microfiber cleaning cloth for safe, gentle cleaning and maintenance.
