Portrait of the English optician John Dollond, 1706-1761. The son of a French Huguenot refugee Dollond was for many years a silk-weaver. In 1752, however, he joined his son Peter in his business as an optician. They attacked the problem of chromatic aberration, i.e. the colour fringes in the images produced by a simple lens, which Newton had considered inherent in lenses. A largely achromatic compound lens had been designed and used in telescopes from 1733. The Dollonds, using improved glass, produced good quality achromatic lenses from 1758, which led to nearly colour-free refracting telescopes and better microscopes being made.
