The NiSi 77mm Ti Enhanced CPL Circular Polarizer Filter helps to reduce reflections & glare by filtering out light that has become polarized due to reflection from a non-metallic surface. The light from the sun naturally becomes partially polarized due to reflecting off electrons in air molecules, causing the light to scatter into what appears as haze. A polarizing filter arranges, & filters, this directionally polarized light perpendicularly to the reflected light, allowing for the absorption of much of this light. This results in a noticeable reduction of glare & reflections from non-metallic surfaces & an increase in the saturation of skies & foliage.
The NiSi 77mm Ti Enhanced CPL Circular Polarizer Filter (Titanium Frame) has enhanced colour compared to a standard CPL which increases the saturation of the scene when used.
The Titanium Alloy Frame is light, hard, anti-corrosive, heat-resisting & with good performance under very low temperature. The density of Titanium is 4.54g／cm3, it’s almost half of the volume of the same weight steel, & the hardness is twice of aluminium. Its good anti-corrosion ability makes it able to endure strong acid & base. Its melting point is 1942K, about 1000k higher than gold & 500k higher than steel. It’s commonly used in the aerospace industry & missiles.
Matte Black inside the frame using electroplating processing to avoid the reﬂection of light. On the outer side of the ring, the turning by diamond cutters shows the original colour of Titanium. It looks great & is elegant.
Ultra High Deﬁnition Optical glass is after precision annealing which effectively eliminates the stress. Each piece of glass passes strictly HD test & reaches the standard for HD photograph with all kind of lens & there is no loss of image quality.
