The invention in the achromatic lens in 1733 partially corrected coloration aberrations existing in the simple lens[11] and enabled the construction of shorter, more useful refracting telescopes.[12] Reflecting telescopes, nevertheless not restricted by the colour problems seen in refractors, were hampered by using rapid tarnishing speculum metal mirrors used over the 18th and early 19th century—a problem alleviated through the introduction of silver coated glass mirrors in 1857, and aluminized mirrors in 1932.
Telescope mirrors are coated with different products depending upon the shade of the light they have to mirror. The Webb mirror, as an example, is coated with a skinny layer of gold in order that it could replicate infrared mild.
