Most of circular filters are made of brass/aluminum frame, but these kind of materials cannot be lightweight and fit easily at the same time. Because of that, NiSi created a Titanium Alloy Frame Pro Nano UV Cut -395. The frame is made of Titanium and the optical glass is Nano coated and extreme high quality. The main features are the lightweight, durability and high definition. It's light, hard, anti-corrosion, heat-resisting, and with good performance under very low temperature. Its good anti-corrosion ability makes it able to endure strong acid and base.
- UV Cut Nano Coating
Nano coating cut the UV light below 395nm, and effectively avoid the fuzziness situation. It makes sure high transmittance and ultralow reflection on the glass surface. It enables the visible light come through evenly and control the color balance. Also there's super strong waterproof coating with anti-scratch ability. It's easier to remove the dust, fingerprint, water stains, and keep the filters clean.
- Matte Black inside the frame
The frame is after matte black electroplating processing to avoid the reflection of light. After the turning by diamond cutters, it shows the original color of Titanium. Fashion and elegant.
- Ultra High Definition
Optical glass is after precision annealing which effectively eliminates the stress. Each piece of glass passes strictly HD test, and reaches the standard for HD photograph with all kind of lens and there is no loss of image quality. Black matte paint is all around the glass edge to avoid the influence caused by stray light.
