NiSi Filter UV SMC L395 95mm

NiSi Filter UV SMC L395 95mm – Ultra-thin UV protection for wide-angle lenses

The NiSi Filter UV SMC L395 in 95mm size reduces ultraviolet light below 395 nm. It uses high-quality Japanese optical glass and double-sided multi-coating to deliver high transmittance and low surface reflection. The filter’s ultra-thin aluminum frame helps prevent vignetting on wide-angle lenses and allows you to use front-mounted accessories.

Key features and benefits

• Ultra thin, only 3 mm: minimizes vignetting effect on wide-angle lenses and fits even on super wide angle optics.
• Multi coating on both sides of the filter: reduces reflections and improves light transmission through the filter.
• High quality optical glass for high transmittance (>98.3%) and highly smooth surface with low reflection (0.5%): maintains image clarity and color fidelity.
• Protects the lens from dust and damage to the front element: acts as a physical barrier for everyday use.
• Hard waterproof and oil repellent coating on outer side: helps repel moisture and oils for easier maintenance.
• Easy to clean: coatings and glass surface simplify regular cleaning routines.

Design and build

The frame uses a high-quality aluminum construction with a thinness of only 3 mm. At this thickness it was described as the thinnest in the world so far. Superfine dull polishing and elaborate knurling ensure the frame resists blanching from repeated rotation. A screw thread on the front of the frame makes it easy to attach a lens cap and additional front-mounted accessories.

Optical performance

This filter cuts ultraviolet light below 395 nm. The Japanese optical glass combined with double-sided multi-coating ensures high transmittance and low reflection, so you retain image sharpness and reduce unwanted flare. The outer hard waterproof and oil-repellent coating further protects the surface and makes routine cleaning faster and safer.

Compliance and materials

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

FAQ

• Question: What exactly does the NiSi UV SMC L395 filter block?
  Answer: It cuts ultraviolet light under 395 nm, reducing UV-related haze while preserving visible light transmission for clearer images.

• Question: Will this filter cause vignetting on my wide-angle lens?
  Answer: The filter’s ultra-thin 3 mm aluminum frame is designed to minimize vignetting and is suitable for use on many super wide-angle lenses to help avoid darkened corners and unwanted reflections.

• Question: How does the finish hold up to repeated use?
  Answer: Superfine dull polishing and deliberate knurling on the frame reduce the risk of blanching from repeated rotation, maintaining a consistent finish during normal handling.

• Question: Is the filter easy to keep clean?
  Answer: Yes. The outer side features a hard waterproof and oil-repellent coating that repels moisture and oils, and the coated glass surface is easy to clean in routine maintenance.

• Question: Can I mount a lens cap or other accessories on this filter?
  Answer: Yes. The front of the frame includes a screw thread that allows you to attach a lens cap and other compatible front-mounted accessories for added protection and flexibility.
