First-surface mirrors are now made for applications requiring a strict reflection without a ghosting effect as seen with a second-surface mirror, where a faint secondary reflection could be observed, coming from the front surface of the glass. This includes most optics applications where light is being manipulated in a specific manner.
A mirror reflecting the image of a vase A first-surface mirror coated with aluminium and enhanced with dielectric coatings. The angle of the incident light (represented by both the light in the mirror and the shadow behind it) exactly matches the angle of reflection (the reflected light shining on the table). 4.5-metre (15 ft)-tall acoustic mirror near Kilnsea Grange, East Yorkshire, UK, from ...
The mirrors are considered one of the eight auspicious items or "ashtamangalyam" used in the entry of a bride at a wedding venue. [4] [1] Chief minister of Kerala Pinarayi Vijayan presented an Aranmula mirror to King Hamad of Bahrain during a visit there in 2017. The British Museum in London has an Aranmula mirror 45 centimeters tall in its ...
In contrast to household mirrors, where the reflecting metal layer is coated on the back of a glass pane and covered with a protective varnish, precision optical equipment like telescopes needs first surface mirrors that can be ground and polished into complex shapes such as parabolic reflectors. For nearly 200 years speculum metal was the only ...

A mirror image (in a plane mirror) is a reflected duplication of an object that appears almost identical, but is reversed in the direction perpendicular to the mirror surface. As an optical effect , it results from specular reflection off from surfaces of lustrous materials, especially a mirror or water .
Comparison of reflections of a pen in an ordinary mirror (left) and two perpendicular mirrors forming the first type of non-reversing mirror (right). The latter also illustrates the visible line in the middle if measures are not taken to minimise it. A non-reversing mirror can be made by connecting two regular mirrors at their edges at a 90 ...
