What is the difference between a Newtonian Telescope and a catadioptric telescope?

Newtonian Telescope vs. Catadioptric Telescope

A Newtonian telescope, also commonly known as a reflector telescope, has one primary thing in common with the catadioptric telescope; they both use two mirrors within the tube body to collect and direct light. The difference lies in the addition of a corrector lens within the catadioptric telescope which fixes any distortion at the edge of the field of view common to a Newtonian telescope. The catadioptric telescope is a blend of the refractor and reflector telescope's components – a combination of the lens and the mirror.
