Heliopan UV Filter 2023 Ø 82 x 0,75 mm | SH-PMC coating
The filters from Heliopan - made in Germany - allows you to produce images of the highest quality - right from the start.
- Heliopan Filter Code 2023
- For brilliant color reproduction, highest contrast and sharpness Heliopan offers:
- The highest quality optical glass from the German Schott Group
- The longest life expectancy thanks to brass filter rims
- Minimal reflections because of matte black filter rings
- At least one high quality hard coating on each filter side to reduce stray light, to maintain high contrast and to avoid flare.
- SH-PMC broadband coatings of 8 layers per side for the highest reflection reduction (below 0.2%) and:
- Dust and moisture repellent top coating on each side of the SH-PMC coated filters for easy cleaning and longest life.
- Made in Germany
- absolutely color neutral
- reliable protection for the lens
- water, grease and oil repellent
- additional internal thread for attaching further filters or lens aperture
The UV blocking filter, also called haze or haze filter is not only an outstanding universal filter for visible improvement of shooting in all types of film, but should always remain as a protection against external influences front of the lens. It absorbs when recording the short-wave component of the interfering scattered light, so that at present extractor a more differentiated reproduction of the environment is possible. The induced by UV-radiation and its strong scattering blur, as well as a bluish to design rendering (bluish), in remote images are eliminated by the colorless UV filters or neutral damped. An exposure extension is not required. In digital cameras, this filter can be used as a protective filter. Because the sensor as opposed to the eye to UV radiation is still remarkably sensitive, it is the diffuse UV radiation in the image as a blue veil again. UV blocking filter can no UV radiation, and helps to more detailed and colorful picture with natural colors, especially in the high mountains and the sea, where the UV radiation is particularly intense. Their action is subsequently replaced by non-digital imaging.
Heliopan SH-PMC Multicoating
The reflection on glass / air surfaces is making a major cause of loss of contrast in objectives, the most demanding in the extreme Photography impossible. Therefore, lens manufacturers operate an enormous effort for the remuneration of their lenses. This quality chain should not break it by using a filter with inferior compensation. With new proprietary systems and technologies Heliopan filters are provided with a much improved remuneration. The existing on each side of each of seven layers broadband coating reduces not only the reflectance in the visible light range to near zero percent, it is also water- and dirt-repellent. This makes it considerably more resistant to injury and easier to clean than previous MC filter or a front lens.
Heliopan SLIM brass mount
The Heliopan filter mounts are precision machined from brass. Brass is dimensionally stable and robust. The brass version does not generate quality-reducing mechanical stresses in the filter glass because of their very low thermal expansion, even under severe temperature fluctuations. Further, the risk of jamming is minimized in the filter thread of the lens. The black coating of brass mount prevents the possible effects of reflections on the socket.
Heliopan used optical glass filter from SCHOTT glass. The filters are manufactured entirely in Germany. Its optical accuracy exceeds that of gelatin filters. The filters are very resistant to aging and fading. modernster through the use of high-tech machines, guaranteed both in metalworking and in optics, is the highest quality
