Heliostat

Description
A heliostat throws sunlight where it might be used for photography or scientific observations. This example has one glass mirror 9.5 cm in diameter, a clockwork mechanism, and a tripod base with leveling screws. The “Gambey à Paris” inscription refers to Henri-Prudence Gambey, a mathematical instrument maker who won a gold medal at the Paris exhibition of 1823 for his heliostat of new construction.
