PolarPro QuartzLine

QuartzLine filters are made from 99.9% pure quartz glass for long durability and optical clarity. These single lens elements produce a very low refractive index of 1.46 and offer excellent temperature stability. The redesigned brass filter frames are easy to screw on and are built to withstand tough adventures.

With optical coatings for a hyper-neutral color profile, nearly optimal target transmission, and multiple coatings for enhanced scratch resistance, water resistance, anti-reflective properties, and reduced vignetting in wide-angle shots, QuartzLine filters enable content creators to achieve lifelike colors for their end products in extreme locations.

The four-part brass frame has been redesigned to ensure a perfect fit for any lens. QuartzLine filters proudly display the outer part of the brass frame while coating the interior in matte black to avoid unwanted reflections.
