The Fringe-Killer (Fringe = colour fringing) blocks unfocused light in the red part of the spectrum (IR) uo to 100% - but above all suppresses over 50% of the interfering stray light in the blue spectral range - without changing the colour impression of the image.
The most delicate details of lunar craters and planetary surfaces can be seen with a much higher contrast.
The Baader Fringe-Killer Color Correction-Filter prevents unwanted colour fringes in both the blue spectral range and in the NIR above 700 nm! The visual impact initially corresponds to a minus violet filter, as opposed to this but the image colour remains broadly balanced. In itself a contradiction in terms? It can only be implemented by applying modern DWDM plasma assisted coating technology, which allows the application of approximately 100 individual layers on a flat-optically polished face surface perfectly and reproducibly without compromising visual quality. This fine optical precision tool also allows inexpensive China-refractors to reach the promised imaging performance. The reduction of chromatic aberration corresponds to what is achieved by corrections-lens systems, which usually cost 20 times more.
