Which mirror is used in telescope?

The Reflecting Telescope or Reflector uses a concave mirror as the telescope’s Primary Objective, rather than a lens or lenses. The type of reflector depends on other system mirror(s), called the Secondary Mirror. A Compound or Catadioptric Telescope uses a combination of Refractor and Reflector characteristics.

Which lenses are used in telescope?

Most refracting telescopes use two main lenses. The largest lens is called the objective lens, and the smaller lens used for viewing is called the eyepiece lens.
