![]() In this story we will discuss the various types of reflectors that were used to create the ‘Mirror of Light’. The first method of projecting and directing the light started with the design of the reflector. Experiments were made with the types of fuel being burned, with the design of the braziers, which held the burning fuel, and with ways to direct or concentrate the light from the fire. Lighthouse designers were constantly looking for ways to produce more light. The major problem with early lighthouses was the small output of light from the wood or coal fires then being used. What is Catoptric? It's from the Greek word (Catoptron) for mirror, or reflection, and the lighthouse illumination system based on the principle of reflection was given the name Catoptric System in English. The use of the sensor on ESA space missions is planned for the late 2020s.This is a story about the Catoptric system of lighthouse illumination. ASTRO® XP consists of an electrical unit and an optical head, for which asphericon was able to manufacture complex mirror optics and a spacer. In addition to autonomous determination of their position, size, weight and temperature resistance are the most important requirements for modern star sensors. With a measurement accuracy of 0.1 arc seconds, ASTRO® XP is ten times more accurate than existing sensors and its innovative optical design also makes it extremely lightweight. On behalf of the European Space Agency (ESA), the company Jena-Optronik developed a novel sensor for autonomous attitude and orbit control of satellites and probes in space. Ultra-precise optics for a star sensor Customer Reference Learn more about our manufacturing capabilities. The achievable roughnesses are, depending on the material and shape, up to 0.5 nm Rq. Thanks to optimized production technologies, high-end finishing such as asphericon ION-Finish TM and Magnetorheological Finishing-Technology® (MRF) as well as high-precision, full-surface and non-contact measurement asphericon manufactures aspheric and parabolic mirrors of the highest quality.ĭepending on the requirements of our customers for aspheric mirrors and aspheric reflectors, accuracies of up to 50 nm global form deviation (irregularity) or 25 nm RMSi are achieved. fused silica, as well as germanium, silicon, zerodur, infrared glass and calcium fluoride. The material is selected according to the customers needs, with the range covering almost all types of glass, e.g.
