Get priceIf your mirror is at all thin for its size, grinding the back of the mirror is just as important as grinding the front! If the back is not flat, the mirror will warp during grinding and polishing, and you will probably end up with ASTIGMATISM, and there is no reason for this, other than carelessness. Therein lies the art of making optics. 1

Get priceBy grinding his own mirrors, using Newton's rings to judge the quality of the optics for his telescopes, he was able to produce a superior instrument to the refracting telescope, due primarily to the wider diameter of the mirror. In 1671 the Royal Society asked for a demonstration of his reflecting telescope.
