In 1894 the glass grinding shop in the Schwabenmühle was founded by Julius Ernst Sill. The grinding machines for glasses , magnifying glasses and reading glasses are powered by the water power of the Pegnitz . As early as 1902, production was expanded and relocated to the Nägeleinsmühle . Lenses for the magic lantern and lighting were also made. In 1912, glass melting furnaces were built for molding pellets . In 1923 production was relocated to Sorg . They began to produce mirrors and large lenses, as well as projection lenses. In 1934 the work was renamed "Optisches Werk Julius Ernst Sill". In 1948 the production of correctal spectacle lenses and lighting lenses for industry began. In 1950 it was expanded to include precision manufacturing for projection, cinema and magnifying lenses. 1959 optical tools of the OHG from Osterode are bought. In 1964 the company Roeschlein, Bad Kreuznach was acquired. Both companies were integrated into JE Sill in 1966 by Hannes Horr. This made it possible to manufacture lenses based on customer drawings. In 1970 the profile projection lenses were developed and in 1978 a sales department was established in the USA . In 1986 the company invested in SyncroSpeed ​​motor controls, founded its own optics calculation and design department, and began producing scan lenses.

Optolyth

In 1856 the optician Johann Georg Sill founded the optical grinding shop JG Sill in the Schwabenmühle in Nuremberg . There he used water power to drive his machines. In 1860 the rooms became too small, he relocated the company after giant step 20, where it remained until the effects of the war in 1945 completely destroyed it. After JG Sill's death, his daughter Maria Roth, née Sill, took over the business, which she ran until 1914. Her son, Emil Casimir Roth, took over the optical grinding shop JG Sill after a good technical training and converted the company into EC Roth . EC Roth's brother was also in the business; both were drafted into military service in 1914, where the brother died as an air officer in 1918. During the First World War , in the absence of EC Roth and his brother, the relatives closed the business, the machines were sold, so that EC Roth had to rebuild the business after his return. In 1922, the newly established company was able to be entered in the commercial register again under the company name "Optical Glass Grinding Emil Casimir Roth". At that time, Roth manufactured optics for optical toys, especially for cheap Galilean binoculars, but also kaleidoscopes and telescopes , some of them working from home. EC Roth had meanwhile passed his master craftsman examination. In the spring of 1945, during an air raid, an air mine reduced operations at the giant step to rubble and ashes. EC Roth had already relocated production to Oed in 1941 , where he had had a business since 1939. The factory in Oed was converted and, in order to escape the chaos of war, production and a small part of the machines were also relocated to Oed. After the currency reform in 1948, Walter Roth began to rebuild the company with the support of his father, EC Roth. The production of reading magnifiers began with just a few employees. There was a quick switch to the production of cheap binoculars. The company later switched to the production of prismatic lenses. The focus of production has always been on optics; From the parts that were cheap at the time, production increased to high-precision optics. The various company names from "EC Roth" to "Walter Roth" were summarized in the 1980s under the general term and symbol "Optolyth".
