NiSi Filter UV Pro Nano Huc 40mm

NiSi Filter UV Pro Nano Huc 40mm – Ultra-thin 3.5mm Brass Frame with Nano Coating

The NiSi Filter UV Pro Nano Huc 40mm combines high-quality Japanese ultraviolet absorption optical glass with a precision brass frame and advanced coatings. It employs double-sided, multi-coating lens technology to ensure excellent light transmission and a smooth surface that reduces unwanted reflections. The filter’s ultra-thin 3.5mm brass construction makes it suitable for use on wide-angle lenses with minimal vignetting.

Advanced optical glass and coatings

The filter uses Japanese ultraviolet absorption optical glass. It features an exclusive creative "U" type Nano coating together with a hardened waterproof coating. These coatings provide a highly smooth surface and improve resistance to water and contaminants, while the multi-coating on both sides helps maintain high transmittance and low reflection.

Protection and practical benefits

The UV filter also works as a general protective filter to leave on lenses at all times. It helps reduce dust and moisture reaching the front element, and it offers extra protection in case of drops or scratching. The surface is easy to clean, helping you maintain clear optics during shoots and in the field.
