NiSi UV SMC L395 77mm Filter

NiSi SMC UV L395 Ultra-Thin Filter

The NiSi SMC UV L395 series features ultra-thin filters made from high-quality Japanese optical glass with a special double-sided multi-layer anti-reflective coating. This coating minimizes reflections and allows more than 98.3% of light to pass through. The filter cuts UV light below 395 nm, effectively reducing ultraviolet radiation that can affect image quality.

Key Features

• Ultra-thin filter ring: Only 3 mm thick, minimizing vignetting on wide-angle lenses.
• Double-sided multi-coating: Applied on both sides of the filter to reduce reflections and enhance light transmission.
• High-quality optical glass: Ensures high light transmittance (>98.3%) and a very smooth surface with low reflection (0.5%).
• Durable aluminum frame: Made from premium aluminum with superfine matte polishing and precise knurling to prevent discoloration from repeated rotation.
• Waterproof and oil-repellent coating: The outer surface is treated to resist water and oil, making the filter easy to clean.
• Protects lens: Shields the front lens element from dust and damage.
• Front thread: Allows easy attachment of lens caps and other accessories.
• Environmentally compliant: All materials meet the European Union's RoHS standards for restriction of hazardous substances.

Technical Specifications

• Filter diameter: 77 mm
• Filter thickness: 3 mm (ultra-thin)
• UV cut-off wavelength: below 395 nm
• Light transmittance: >98.3%
• Reflection rate: approximately 0.5%

Applications

This ultra-thin UV filter is ideal for use on wide-angle and super wide-angle lenses to prevent vignetting and unwanted reflections while protecting the lens from UV light and physical damage.
