reflecting telescope gathers light from mirror
The telescope described is an optical telescope. If the primary optic is a mirror, it's a reflector, and it the primary optic is a lens, it's a refractor.
The Hubble telescope was a basic reflector telescope with a 94.5 ft mirror. The Hubble collects light though its open end, the primary mirror reflects the light to a secondary mirror that then reflects the light through a hole in the primary mirror to a focal point of the instruments or eyes of the Hubble.

The telescope is cylindrical. Its primary mirror is concave.

A parabolic mirror, usually. A spherical mirror is also sometimes used, but that requires additional corrections in other parts of the telescope.

There are a variety of places where one can buy a new mirror for a telescope. The best place to get a replacement mirror is at a online shop that sells telescopes.

No, it isn't. The Hubble Space Telescope is a reflector. It has a primary mirror, and not a primary lens.
