2. Schmidt camera - Wikipedia

   en.wikipedia.org/wiki/Schmidt_camera

   The Mersenne–Schmidt camera consists of a concave paraboloidal primary mirror, a convex spherical secondary mirror, and a concave spherical tertiary mirror. The first two mirrors (a Mersenne configuration) perform the same function of the correcting plate of the conventional Schmidt. This form was invented by Paul in 1935. [24]

A simpler mirror may reflect 99.9% of the light, but may cover a broader range of wavelengths. Almost any dielectric material can act as a perfect mirror through total internal reflection. This effect only ...

   en.wikipedia.org/wiki/Dielectric_mirror

   Dielectric mirrors are also used to produce ultra-high reflectivity mirrors: values of 99.999% or better over a narrow range of wavelengths can be produced using special techniques. Alternatively, they can be made to reflect a broad spectrum of light, such as the entire visible range or the spectrum of the Ti-sapphire laser.
