The Corrective Optics Space Telescope Axial Replacement (COSTAR) is an optical correction instrument designed and built by NASA. It was created to correct the spherical aberration of the Hubble Space Telescope ' s primary mirror , which incorrectly focused light upon the Faint Object Camera (FOC), Faint Object Spectrograph (FOS), and Goddard ...
As part of the corrective service mission (STS-61 in December 1993) the WFPC was swapped out for a replacement version. The Wide Field and Planetary Camera 2 improved on its predecessor and incorporated corrective optics needed to overcome the main mirror defect. To avoid potential confusion, the WFPC is now most commonly referred to as WFPC1.
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 ...
In the early 10th century, the Persian scientist al-Razi described ways of silvering and gilding in a book on alchemy, [citation needed] but this was not done for the purpose of making mirrors. Tin-coated mirrors were first made in Europe in the 15th century. The thin tinfoil used to silver mirrors was known as "tain". [5]
Between 1845 and 1849, Sims performed dozens of surgeries, without anesthesia, on at least 12 enslaved women. In these experiments, Sims developed a technique to repair fistula and in the process invented the duckbill speculum. These experiments, and the development of the modern specula, led some to regard Sims as the "father of modern ...

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).
