That instrument, an even more expensive space telescope, will require some means of blocking the light from a star in order to detect light reflected by its planet.
牛顿望远镜和反射折射望远镜都有一个次级反射镜(或称斜反射镜)，它们阻挡了一部分主反射镜的发射光。
Newtonian and catadioptric telescopes have secondary (or diagonal) mirrors that obstruct a small percentage of light from the primary mirror.
那些不利用反射的望远镜利用的是折射。
Those telescopes that do not employ reflection use refraction.
