Antique optician's trial lens set, circa 1900. In 1845, Emil Busch inherited the family business "Optische Anstalt Rathenow", founded in 1801. In 1852, the production of cameras began. In 1872, the company changed its name to "Emil Busch AG". Busch used Zeiss lenses for his objectives. In 1896, the city of Rathenow, where the company was based, was one of the most important centers in Germany for the optical industry. In 1927, Zeiss acquired the majority of shares in Emil Busch AG. Emil Busch stopped producing lenses and continued only the production of cameras. At the end of World War II, the company was destroyed. The oak wood box is in excellent condition with working closing hooks. Inside, the upper part is covered with red satin with the marking "Bush", while in the lower part there are several compartments containing trial lenses of different convex and concave gradations as well as other trial lenses. The set is almost complete and 5 convex lenses are missing (visible in the photo). There is also a pair of lenses for calculating the interpupillary distance and a pair of adjustable glasses "Oculus Universal Messbrille".
