NiSi Filter Protector Pro Nano Huc 95mm

NiSi Filter Protector Pro Nano Huc 95mm – Ultra-thin 3.5mm Aluminum Frame with Dual-Sided Nano Coating

The NiSi Filter Protector Pro Nano Huc 95mm gives your lens front element reliable protection while preserving image clarity. It uses high quality optical glass with nano coating on both sides to maintain excellent light transmission. The frame is made of high quality aluminum and measures only 3.5mm in thickness, which helps the filter sit close to the lens and reduces the risk of vignetting on wide-angle optics.

Design and build

The filter combines a thin, durable aluminum frame with precision surface finishing. Superfine dull polishing and elaborate knurling ensure the frame will not blanch from repeated rotation. Because the frame is ultra thin, it fits well even on super wide angle lenses where vignetting is a concern.

Optical performance and coatings

NiSi uses high quality optical glass and applies an exclusive "U" type Nano coating on both sides of the glass. This treatment reduces surface reflection and allows the glass to transmit the majority of incoming light. In addition, a hardened waterproof coating protects the outer surface and makes the filter easy to clean.

Key features

• Ultra thin frame (3.5mm) to minimize vignetting on wide angle lens.
• High quality optical glass for high transmittance (99.3%) and a highly smooth surface with only 0.3% reflection.
• Exclusive creative "U" type Nano coating.
• Hardened waterproof coating.
• Protects the lens from dust and damage to the front element.
• Easy to clean.

Practical benefits

Use this protector to shield your front element from dust, accidental impacts, and contact damage while shooting. The dual-sided nano coating and hardened waterproof layer simplify maintenance and cleaning. Meanwhile, the ultra-thin 3.5mm frame reduces the chance of vignetting when used on wide-angle lenses.

FAQ

Question: Will this protector cause vignetting on wide-angle lenses?
Answer: The ultra-thin 3.5mm aluminum frame is designed to minimize vignetting and to fit well on super wide angle lenses, helping preserve the image corners.

Question: How does the coating affect cleaning and water resistance?
Answer: The filter has a hardened waterproof coating and a dual-sided Nano coating that both protect the surface and make the filter easy to clean, so dust and smudges are simpler to remove.

Question: Will the protector change image quality or light transmission?
Answer: The protector uses high quality optical glass and nano coatings to maintain high transmittance (99.3%) with a low surface reflection (0.3%), keeping image quality and light throughput largely unaffected.

Question: Is the frame durable and will it show wear from repeated use?
Answer: The frame is made from high quality aluminum and features superfine dull polishing plus elaborate knurling to prevent blanching from repeated rotation, improving long-term durability.
