Why is it important to keep temperature of telescope mirror or lens canstant?

It's important to keep a constant temperature because materials expand or contract depending upon how hot they are. Should one region of the telescope become hotter than the rest, it will change it's shape more, and distort the mirror, reducing the clarity of any images.

Does a reflecting telescope gather light with a lens or a mirror?
reflecting telescope gathers light from mirror
What telescope has an eyepiece lens and a 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.
What type of telescope is the hubble telescope?
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.
