Telescope (detail)
Add to album

This is a detail of a refracting telescope made between 1761 and 1766, probably by Peter Dollond (1731-1820), a scientific instrument maker based in London.

The single draw is marked 'P. DOLLOND/ Strand/ LONDON'.

In 1758, Dollond's father, John, a Spitalfields weaver, patented his achromatic doublet lens. In 1765, a further improvement was made by Dollond himself using a double-concave flint glass cemented to two double convex lenses of crown glass. However, the patent was disputed by other London optical instrument makers, although not very successfully.
