Description
This 'Culpeper'-type microscope was made by the London scientific instrument maker Robert Brettell Bate (1782–1847) in around 1820. It is based on a popular design style pioneered by the microscope-maker Edmund Culpeper.

Edmund Culpeper, an instrument maker and engraver of outstanding quality developed the tripod compound microscope in the early 18th century. He mounted the body on two tiers with tripod legs and added a mirror below the stage ( the part that holds the specimen). This made it possible to illuminate the specimen from below without having to hold the instrument to the light.

The 'Culpeper' form of microscope quickly became immensely popular and the design was copied by all the leading instrument makers of the 18th century. The materials used gradually changed as the century progressed, from leather, wood and brass, to all brass by 1800.
