NiSi Filter UV Armor FX Pro Nano L395 46mm

NiSi Filter UV Armor FX Pro Nano L395 46mm – Explosion-Proof Protective UV Shield

The NiSi UV Armor FX Pro Nano L395 46mm provides explosion-proof protection and UV filtration for your lens. It combines a laminated safety design with optical coatings to protect the front element while maintaining image clarity.

Explosion-proof laminated construction

NiSi Armor FX adopts the explosion-proof laminated design used in high-end automobile front windshields. As a result, the glass can remain cracked without shattering after a strong impact. Therefore, the filter avoids the formation of loose glass fragments and minimizes the risk of scratches to the front element and lens coatings.

Additionally, this design comes from NiSi’s explosion-proof cinema filter line, which is widely used for high-end cinema lenses.

Frame design and handling

The filter features a distinct mechanical design that makes it easy to fit and remove while avoiding vignetting on wide-angle lenses.

• Unique twill Brass frame with a patented two-color design.
• Ultra-slim 3.9 mm frame profile to reduce the risk of vignetting, including use at 14mm (full frame).
• Knurling on the frame provides a better grip for installation and removal.
• Front filter thread for added convenience and mounting of additional accessories.

Optical characteristics and coatings

This UV filter absorbs ultraviolet light with wavelengths below 395 nm. By reducing UV interference, it improves image clarity in conditions where UV light would otherwise affect the image.

The filter uses double-sided nano coatings with multi-layer low-reflection treatment. These coatings deliver a high transmittance rate and reduce glare and ghosting artifacts. In addition, the double-sided nano coatings are waterproof and oil-proof, which helps protect the lens from dust and makes the filter easy to clean.

NiSi specifies that the Armor FX series uses CINE optical glass designed to avoid loss of sharpness, so the protective layer does not compromise image detail.

Practical benefits and use cases

• Protects the front element and coatings from impact, dust, and handling wear.
• Suitable for shooting in a wide range of scenes where front-element protection and UV filtration are needed.
• Designed with cinema-grade considerations and compatible with high-end cinema lens workflows.
• Maintains optical performance while providing a protective shield that is easy to clean and handle.

FAQ

question: How does the explosion-proof design protect my lens?
Answer: The laminated explosion-proof construction prevents the formation of loose glass fragments after impact. Therefore, it minimizes the risk of scratching the front element and its coatings while keeping the front surface intact.

question: Will this filter affect image quality or sharpness?
Answer: No. The Armor FX series uses CINE optical glass and double-sided nano coatings with multi low-reflection treatment, providing up to 99% transmittance and designed to avoid loss of sharpness. The coatings also reduce glare and ghosting.

question: Is the filter easy to install and clean?
Answer: Yes. The ultra-slim 3.9 mm frame with knurling improves grip for easy installation and removal, and the front filter thread adds convenience. The double-sided waterproof and oil-proof nano coatings make the filter super-easy to clean and help protect against dust and smudges.

question: Can I use this on wide-angle lenses without vignetting?
Answer: Yes. The filter’s ultra-slim frame is designed to avoid vignetting, including use at 14mm on full-frame cameras, according to the product information.
