NiSi Filter UV SMC L395 62mm

NiSi Filter UV SMC L395 62mm – Ultra-thin 3 mm UV filter that cuts UV light below 395 nm

The NiSi Filter UV SMC L395 is a 62mm UV filter designed to cut ultraviolet light below 395 nm. It uses high-quality Japanese optical glass and multi-coating on both sides to maintain high transmittance and low reflection. The filter’s ultra-thin aluminum frame measures only 3 mm and suits wide-angle lenses to minimize vignetting and unwanted reflections.

Design and materials

The filter glass is Japanese optical glass, chosen for its high transmittance and smooth surface. NiSi applies a double-sided multi-coating (SMC) to reduce reflections and preserve image clarity. In addition, the outer side of the filter has a hard waterproof and oil-repellent coating, which makes the surface easier to clean and helps resist fingerprints and moisture.

The frame uses high-quality aluminum and is exceptionally thin at 3 mm. This thin frame helps the filter fit closely to super wide-angle lenses so you avoid vignetting. Moreover, NiSi applies superfine dull polishing to the frame and adds elaborate knurling. These finishings prevent the frame from blanching or showing wear even after repeated rotations.

Functionality and practical details

This UV filter cuts ultraviolet light under 395 nm, reducing UV haze in your images. With transmittance greater than 98.3% and low surface reflection of 0.5%, the filter maintains light throughput while keeping reflections to a minimum. The front of the frame includes a screw thread, which makes it easy to attach a lens cap and other front-mounted accessories.

• Ultra thin, only 3 mm: minimizes vignetting on wide-angle lenses
• Multi coating on both sides of the filter: reduces reflections and preserves image quality
• High quality optical glass for high transmittance (>98,3%) and a highly smooth surface with low reflection (0,5%)
• Protects the lens from dust and damage to the front element
• Hard waterproof and oil repellent coating on the outer side: easier to clean and resistant to moisture and oils
• Easy to clean: coatings and smooth glass surface facilitate maintenance

Standards and safety

All materials used in this filter meet the European Union’s ROHS (Restrictions on Hazardous Substances) requirements. The product contains no hazardous substances as defined by those standards.

FAQ

Question: Will this filter cause vignetting on wide-angle lenses?
Answer: The NiSi UV SMC L395 features an ultra-thin 3 mm aluminum frame specifically to minimize vignetting on super wide-angle lenses. Its slim profile reduces the chance of dark corners while still providing UV protection.

Question: How does the filter affect image quality and light transmission?
Answer: The filter uses Japanese optical glass with double-sided multi-coating, giving transmittance greater than 98.3% and surface reflection of only 0.5%. These characteristics help maintain image clarity and light throughput while reducing reflections and UV haze.

Question: Is the filter easy to maintain and keep clean?
Answer: Yes. The outer surface has a hard waterproof and oil-repellent coating that repels moisture and oils, making the filter easier to clean and maintain. The smooth coated surface resists fingerprints and debris.

Question: Can I attach lens caps or other accessories?
Answer: The front of the frame includes a screw thread, so you can fit a lens cap and other front-mounted accessories directly onto the filter for convenient use.

Question: Are the materials safe and compliant with environmental standards?
Answer: All materials used in the NiSi UV SMC L395 meet the European Union’s ROHS requirements and do not contain hazardous substances as defined by those standards.
