Optical Instrument & Equipment

Bille and his team work with an optical instrument called an active mirror—a device used in astronomical telescopes to spot newly emerging stars and far distant galaxies.

比尔和他的团队使用一种被称为“活动镜”的光学仪器，这是一种在天文望远镜的种类中用来发现新出现的恒星和遥远星系的仪器。

Galileo did not invent the telescope, but on hearing, in 1609, that such an optical instrument had been made, he quickly built his own device from an organ pipe and spectacle lenses.

伽利略并没有发明望远镜，但在1609年听到有人制造了这种光学仪器后，他很快用管风琴管和眼镜镜片制造了自己的望远镜。
