Telescope (detail)
This is a detail of a refracting telescope made in 1765, probably by Peter Dollond, a scientific instrument maker based in London.
The detail shows the inscription on the telescope's single brass draw tube. It reads 'PETRUS DOLLOND/ Ann. Dom. 1765/ LONDINIUM'.
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.
