由于现代天文望远镜继续随巨型多块反射镜等现代设计和变形光学而发展,加拿大拉瓦尔大学的一个光学研究组正在悄悄把老概念变成用于大孔径望远镜的高技术、低成本的选择方案。该校的E. F. Borra已在制作直径高达2.5m优质光学液体反射镜方面取得成功。作 As modern astronomical telescopes continue to evolve with modern designs and metamorphic optics such as giant multi-mirrors, an optical research group at Laval University in Canada is quietly turning the old concept into a high-tech, low-cost option for large aperture telescopes . The school’s E. F. Borra has been successful in producing high-quality optical liquid mirrors up to 2.5 m in diameter. Make
