NiSi UV Pro Nano HUC UV Filter 40.5mm

NiSi PRO Nano HUC UV Filter

The NiSi PRO Nano HUC UV filter features ultra-thin design with double-sided, multi-coating lens technology using high-quality Japanese ultraviolet absorption optical glass. This ensures high light transmittance (>99.2%) and a highly smooth surface that minimizes reflection to only 0.3%.

The filter frame is precision-crafted from brass with a thickness of only 3.5mm, making it ideal for use on super wide-angle lenses by minimizing vignetting effects. The filter surface is treated with an exclusive "U" type Nano coating and a hardened waterproof coating, providing exceptional durability against water and oil, and making it easy to clean.

Key Features

• Ultraviolet absorption optical glass for effective UV filtering
• Brass frame constructed with highly accurate brass milling
• Exclusive "U" type Nano coating for enhanced surface durability
• Hardened waterproof coating for resistance to water and oil
• Top-level optical surface machining accuracy
• Ultra-thin 3.5mm frame to minimize vignetting on wide-angle lenses
• High-quality optical glass ensuring high transmittance (>99.2%) and minimal reflection (0.3%)
• Protects lens from dust, moisture, and physical damage to the front element
• Easy to clean surface

This UV filter also serves as a general protective filter to be left on the lens at all times, helping to reduce dust and moisture ingress and providing additional protection against drops or scratches.
