High-energy-density ultrasound with around 20 times amplification by two parabolic reflectors propagates through the thin waveguide between 1 to 2 MHz, and wideband large mechanical vibration at the waveguide tip from 1 kHz to 2.5 MHz accelerates the therapeutics. Here, we invent double-parabolic-reflectors acoustic waveguides, where high-power ultrasound emission and large mechanical vibration enhance the therapeutic efficiency. Although acoustic waveguides are commonly inserted into tissue for localized therapy, powerful ultrasound delivery is difficult. However, ultrasound penetration depth is shallowed with increasing frequency which limits the therapeutic accuracy for deep tissues. The use of the sensor on ESA space missions is planned for the late 2020s.High intensity focused ultrasound therapeutics are widely used to noninvasively treat various types of primary tumors and metastasis. 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.

Space exploration and attitude determinationĭepending on the material used, both CNC technologies of grinding and polishing, as well as diamond turning, are used in the production of aspherical on- and off-axis optical mirrors as well as reflectors.
