The antireflective coating on the telescope lenses are usually made of magnesium fluoride. The mirror of the telescope can be made from a strong, temperature-resistant glass such as Pyrex. They use these Pyrex so that light can easily pass through it (the mirror)

What are most of these telescopes made out of and why do they use that material?
