2. Non-reversing mirror - Wikipedia

   en.wikipedia.org/wiki/Non-reversing_mirror

   The Museum of Illusions refers to this type of mirror as an "antigravity mirror" because as it rotates once around the line-of-sight axis, the reflected image rotates twice, appearing upside-down when the joint is horizontal. Another type of non-reversing mirror can be made by making the mirror concave (curved inward like a bowl).

3. First-surface mirror - Wikipedia

   en.wikipedia.org/wiki/First-surface_mirror

   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 ...

6. Mangin mirror - Wikipedia

   en.wikipedia.org/wiki/Mangin_mirror

   Since light passes through the glass twice, the overall system acts like a triplet lens. [4] The Mangin mirror was invented in 1874 [1] by a French military engineer named Colonel Alphonse Mangin as a substitute for the more difficult to manufacture parabolic reflecting mirror for use in searchlights. Since the catadioptric design eliminated ...

7. Silvering - Wikipedia

   en.wikipedia.org/wiki/Silvering

   When glass mirrors first gained widespread usage in Europe during the 16th century, most were silvered with an amalgam of tin and mercury, [6] In 1835 German chemist Justus von Liebig developed a process for depositing silver on the rear surface of a piece of glass; this technique gained wide acceptance after Liebig improved it in 1856.
