Rollei Premium RoundUV Filter
UV filters are among the optical lens attachments, which are still used today. Mainly the special filters ensure that the ultraviolet component in the sunlight is purposefully blocked and that it can’t lead to inadvertent colour distortions. The UV light, which is invisible to the human eye, can also have a slightly disturbing effect on the sharpness of the image and is especially annoying in the case of powerful detail enlargements in particular. However, in addition, a UV filter has concrete mechanical advantages. Due to its otherwise image-neutral characteristics it can remain on the lens for a long time and protects expensive lenses against damage.
Gorilla®* glass - the bodyguard for your lens
The Rollei Premium RoundUV Filter is supplied in nine different lens diameters: 49, 52, 55, 58, 62, 67, 72, 77 and 82 mm. This high-quality round filter protects the front disc from mechanical stress, scratching, dirt and sand. The Gorilla glass from the well-known specialist manufacturer, Corning Inc., from the US Federal State of New York enjoys a legendary reputation by now and is already used for high-quality electronics and photography products. Ions are exchanged on the molecular level by an extremely hot bath in a specially mixed liquid and lend the glass extreme resistance. Even with deep scratching there is no splintering of the material on the edges and further impairment of the filter surface is certainly prevented.
Luminance Coating - the additional protective layer
The filter blanks are subjected to yet another coating. The Luminance Coating almost fully reduces reflections and mirror images but lets the light pass through almost completely and in an absolutely colour neutral manner. In addition, oil, water or dirt is simply repelled, damage due to mechanical effects is significantly reduced and an uncompromising colour fidelity is guaranteed from the moment of the shot to the time that it is saved. Each phase of development from the personal sample release by the Rollei experts up to the final delivery to our customers is monitored in the most stringent way and the merciless exclusion criteria were developed by Rollei itself.
