NiSi Filter Pro Nano AIR UV 77mm

NiSi Filter Pro Nano AIR UV 77mm – 99.9% Transmission for Crystal-Clear Lens Protection

The NiSi Pro Nano AIR UV 77mm filter preserves image clarity while protecting your lens. It uses NiSi’s ULRC (Ultra Low Reflective Coating) technology to keep light transmission extremely high and reflections very low. As a result, the filter offers optical protection without noticeably affecting image quality.

High Transmission and Low Reflectivity

The Air UV filter reaches a peak transmission of 99.9%, which keeps the view through the filter nearly as clear as looking through air. Additionally, it features minimal reflectivity at just 0.1% and an average transmission of 99.6% across the 420–680 nm range. These measured values help ensure that your lens maintains high light throughput and minimal internal reflections.

Designed for High-Resolution Imaging

This filter supports cameras and lenses that exceed 100 megapixels. Therefore, it preserves fine detail and sharpness for landscape, portrait, and commercial photography workflows that demand high resolving power. In short, the filter is engineered to handle high-resolution capture without degrading image definition.

Durable 48-Layer ULRC Nano-Coating

NiSi applies a 48-layer ULRC nano-coating to the glass surface. This multilayer coating enhances durability and provides several protective properties:

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

These coating characteristics make the filter suitable for outdoor use and help it resist the wear and contamination common in demanding shooting conditions.

UV Blocking and Color Integrity

The filter blocks ultraviolet light below 395 nm. By reducing UV-induced interference and blue haze, it helps preserve color accuracy and image clarity in situations where UV light could otherwise affect results. This makes the filter useful for shooting in bright, UV-prone environments.

Optical Glass and Frame Construction

The NiSi Air UV uses carefully selected premium lens optical glass to maintain consistent optical performance. Each piece of glass is subject to strict quality control to support reliable imaging results.

The frame is made from brass, offering greater resistance to deformation compared with typical aluminum frames. The ultra-thin knurled brass design aids easy mounting and removal, while the slim profile helps prevent vignetting even on ultra-wide-angle lenses.

Quality Control and Testing

Every NiSi Pro Nano AIR UV filter undergoes strict inspection. NiSi verifies transmission and reflectivity using a Shimadzu spectrophotometer to ensure each unit meets specified optical standards. This testing process delivers consistent, measurable performance from filter to filter.
