PolarPro Quartzline UV Filter This important filter blocks UV radiation. As a result, it ensures - especially in places with clean air (such as high mountains or at the sea) - more brilliant images. Without a UV blocker, the UV radiation would result in blue-hazy images. An additional benefit not to be sneezed at is the protection of the front lens. Therefore, you can leave this UV filter from PolarPro permanently on the lens. High quality quartz glass PolarPro Quartzline filters are made entirely of 99.9% pure quartz glass, which ensures unparalleled durability and clarity. The glass has a very low refractive index of only 1.46, so there is no loss of sharpness when using this filter. In addition, quartz glass is also extremely temperature resistant and is ideal for sensors up to 100 megapixels. Simply perfect for photographers and filmmakers who like to work under extreme conditions! 16-fold multi-coating Each quartz filter glass is coated with 16 wafer-thin layers. The different coatings ensure, among other things, optimum scratch, water and grease resistance, avoidance of reflections and a strong reduction of the risk of vignetting. In addition, they ensure very high light transmission and hyper-neutral colour rendition. Filter mount made of robust brass A well-known problem with many filters is that they jam when screwed into the lens thread if they are not fitted exactly. Especially mounts made of aluminium or even plastic are easily damaged. The filter mounts of the PolarPro Quartzline are therefore made of robust brass. This high-quality metal makes screwing in and unscrewing much easier. And by the way, this gold-coloured filter frame also looks luxurious and aesthetic.
