An old engraving of Victorian polariscope. It is from a book of the 1890s on discoveries and inventions during the 1800s. The polariscope is an optical inspection device used to detect whether or not light is polarised. A polariscope is composed chiefly of a light source, mirrors and two polarising lenses. The French astronomer Dominique François Jean Arago invented the polariscope in 1811.
