The 77mm QuartzLine UV Filter from PolarPro is a general-use, clear filter designed to absorb ultraviolet light and reduce the bluish cast of daylight. Aside from the reduction of unwanted blue casts, no additional coloration or contrast is created, and adjustments to exposure are not required while using this filter.
This filter is constructed from quartz glass for enhanced durability. To prevent internal ghosting and reflections, eight layers of anti-reflection coatings offer scratch protection to the filter surface while promoting clarity and color fidelity. The coatings associated with the PolarPro 77mm QuartzLine UV Filter also result in an improved beading effect when in contact with water or oil, allowing for more efficient cleaning.
The quartz glass is set within a brass filter ring with side knurlings. Together, the brass material and knurlings prevent jamming and provide additional strength as well as a textured grip when mounting or removing this filter from a lens.
