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 ...
They are first-surface mirrors, where the immediate bronze surface is flat, plain and highly polished to be reflective, rather than second-surface mirrors, like modern glass mirrors, where the reflection comes from a backing applied to the glass.

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 ...

Thus reflection is a reversal of the coordinate axis perpendicular to the mirror's surface. Although a plane mirror reverses an object only in the direction normal to the mirror surface, this turns the entire three-dimensional image seen in the mirror inside-out, so there is a perception of a left-right reversal. Hence, the reversal is somewhat ...
