NiSi Filter Pro Nano AIR UV 62mm

NiSi Pro Nano AIR UV 62mm – 99.9% Transmission for Crystal-Clear Imaging

The NiSi Pro Nano AIR UV 62mm filter preserves lens clarity while protecting your optics. It uses NiSi’s ULRC (Ultra Low Reflective Coating) to deliver extremely high light transmission and low reflectivity. As a result, you keep image quality intact while adding a protective layer to your lens.

High transmission and low reflectivity

The Air UV Filter achieves a 99.9% peak transmission rate. Furthermore, it shows minimal reflectivity of just 0.1% and an average transmission rate of 99.6% between 420–680nm. Consequently, the filter remains almost as transparent as air and reduces the risk of flare or loss of contrast caused by reflections.

Designed for very high-resolution cameras

The filter supports cameras and lenses that exceed 100 megapixels. Therefore, it maintains resolution and sharpness for demanding work such as landscape, portrait, and commercial photography where fine detail matters.

Advanced ULRC nano-coating and durability

NiSi applies a 48-layer ULRC nano-coating to the filter glass. This multilayer treatment delivers several practical protective properties:

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

Because of these coatings, the filter stands up to challenging outdoor conditions and routine handling, while remaining easier to clean and maintain.

UV blocking to reduce interference

The Air UV Filter blocks ultraviolet light below 395nm. As a result, it helps reduce UV-induced haze and color shifts, improving color accuracy and image clarity in bright or high-altitude conditions where UV interference can occur.

Optical glass and frame design

The filter uses premium, rigorously selected lens optical glass to preserve image integrity. In addition, NiSi mounts the glass in an ultra-thin brass frame with knurling.

• The brass frame offers greater resistance to deformation compared to aluminum frames.
• Knurling on the frame makes the filter easier to mount and remove.
• The ultra-thin design minimizes the risk of vignetting, even with ultra-wide-angle lenses.

Quality control and testing

Each NiSi Pro Nano AIR UV filter undergoes strict inspection. NiSi verifies transmission and reflectivity using a spectrophotometer for consistent optical performance. Specifically, testing includes measurement with a Shimadzu spectrophotometer to ensure the stated transmission and reflectivity figures.

Use cases and outdoor suitability

The Air UV Filter provides lens protection from dust, scratches, and moisture while retaining the full imaging potential of high-quality lenses. Consequently, it is suitable for landscape, travel, and outdoor photography where protection and optical clarity are both required.

FAQ

Question: Will the 62mm NiSi Pro Nano AIR UV filter affect image sharpness?
Answer: No. The filter is designed for use with high-resolution cameras and lenses, including those exceeding 100 megapixels, and the high transmission and low reflectivity are intended to preserve sharpness and detail.

Question: How does the ULRC coating help in the field?
Answer: The 48-layer ULRC nano-coating provides scratch, stain, water, and oil resistance. Therefore, it makes the filter easier to clean and more resistant to environmental wear during outdoor shooting.

Question: Will this filter cause vignetting on wide-angle lenses?
Answer: The filter uses an ultra-thin brass frame specifically to reduce the risk of vignetting, even when using ultra-wide-angle lenses.

Question: How does the filter improve color and clarity in bright conditions?
Answer: By blocking UV light below 395nm and maintaining high transmission in the visible range, the filter reduces UV-induced haze and helps keep colors accurate and images clearer in bright or high-altitude environments.

Question: What comes in the package with the 62mm filter?
Answer: The package contains the NiSi Pro Nano AIR UV filter in 62mm size and a NiSi Microfiber Cleaning Cloth for maintenance.
