(I) Most modern mirrors consist of a thin layer of
aluminium deposited on a sheet of glass. (II)
They are also used in scientific apparatus such
as telescopes and lasers, and in industrial
machinery. (III) They are back silvered, where
the reflecting surface is viewed through the
glass sheet. (IV) This makes the mirror durable,
but lowers the image quality of the mirror due to
extraneous reflections from the front surface of
the glass. (V) This type of mirror reflects about
80% of the incident light.
