Dollond, John (10.06.1706–30.11.1761) was an English optician and a Fellow of the Royal Society (1761). Born in London. He was a weaver of silk fabrics. In 1752 he founded a workshop for optical instruments.
In 1757 he made an achromatic objective consisting of a converging lens of crown glass combined with a diverging lens of flint glass, and in 1758 an achromatic objective made up of three lenses. In 1758 he built the first achromatic telescope, which came into wide use, and in 1754 a heliometer.
