NiSi Filter UV SMC L395 40.5mm – Cuts UV light under 395 nm with ultra-thin 3 mm frame
The NiSi Filter UV SMC L395 40.5mm blocks ultraviolet light below 395 nm while keeping visible light transmission high. It uses high-quality Japanese optical glass and a specially designed ultra-thin aluminum frame. As a result, the filter fits well on wide-angle lenses and reduces the risk of vignetting and unwanted reflections.
Key features
- Cuts UV light under 395 nm to reduce UV haze in images.
- Ultra-thin 3 mm aluminum frame to minimize vignetting on wide-angle lenses.
- Double-sided multi-coating for improved light transmission and reduced reflections.
- High-quality Japanese optical glass with high transmittance (>98.3%) and low reflection (0.5%).
- Front screw thread to accept lens caps and additional accessories.
- Hard waterproof and oil-repellent coating on the outer side for easier cleaning and everyday protection.
- ROHS-compliant materials that meet EU environmental standards.
- Fine polishing and knurling on the frame to prevent blanching from repeated rotation.
Materials and build
The filter uses high-quality Japanese optical glass to ensure high transmittance and a smooth surface. Moreover, the glass receives multi-coating on both sides to lower reflections and enhance image clarity.
The frame is made from aluminum and measures only 3 mm in thickness. Because of this slim profile, the filter suits super wide-angle lenses and helps avoid vignetting and reflections. Additionally, the frame has superfine dull polishing and knurling so the finish will not blanch after repeated use.
Practical benefits and handling
Use the front screw thread to attach your lens cap or other threaded accessories. The outer side features a waterproof and oil-repellent coating, so you can clean the filter more easily and keep the front element protected from dust and light damage.
Furthermore, all materials meet ROHS standards, meaning the filter contains no hazardous substances listed under EU environmental regulations.
