The Petrographic Laboratory of the Institute of Applied Mineralogy was headed by V. V. Arshinov.
The stage was developed in 1932-1934 by V. V. Arshinov.
In 1936, experimental production workshops were established at the Central Research Laboratory of Gemstones of the Russkiye Samotsvety Trust. A year later, these workshops became an independent enterprise. In 1945, by order of the NKMP of the USSR, the workshops were transformed into the Experimental Optical-Mechanical Plant of the Russkiye Samotsvety Trust. In 1957, by order of the USSR Council of Ministers, the Russkiye Samotsvety Trust was dissolved, and the Experimental Optical-Mechanical Plant was transferred to the Mechanical Engineering Department of the Leningrad Council of the National Economy. Five years later, in 1962, the Experimental Optical-Mechanical Plant became part of LOOMP (renamed LOMO in 1965) as Production Unit No. 4. Universal stages produced by the trust typically bear the stamp of the Experimental Optical-Mechanical Plant.
This stage, numbered 009, was produced for MP-series microscopes.
The stage has the number 2 and was produced in 1948 for the MP-series microscopes.
The stage has a centering base, it was produced in 1958 for the MP-series microscopes and has the number 0004.
Designed for work according to the Fedorov–Emmons–Zavaritsky method. The stage comes with a set of glass segments in frames (upper and lower) with a radius of 13.5 mm with different refractive indices. The set of accessories could be expanded with objectives and upper Schmidt segments for work using the Sander method.
The stage has the number 0289 and was produced in 1948.
Designed for work according to the Fedorov–Zavaritsky method. The stage has the number 0525 and was produced in 1948.
The most common model of universal stage produced by the Russkiye Samotsvety Trust. The stage has the number 2458 and was produced in 1950.
The stage is a modification of the FS five-axis stage. The spring mount simplifies the removal of the upper segment. In addition, the stage was equipped with upper segments differing in frame construction.
The stage has the number 2988 and was manufactured in 1951.
Designed for works according to the Vardanianets method. The stage is distinguished by a change in the order of the axes. The set of the stage includes a condenser CSF and three achromatic objectives.
The stage has the number 035 and was produced in 1959.
The stage was created by B. F. Timofeev together with I. A. Andin (1960-1961) for use in micropaleontological practice.
The stage has the number 025 and was produced in 1963.
Three times the Order of Lenin Leningrad Optical-Mechanical Association named after V. I. Lenin is a Russian company engaged in the production and sale of optical-mechanical and optoelectronic devices. An enterprise of the optical-mechanical industry of the USSR. The largest Soviet optical-mechanical production and design association.
The most common model of the universal stage produced by LOMO. The stage has the number 640176 and was produced in 1964.
The stage has the number 700115 and was produced in 1970 for microscopes MIN-4, MIN-8, and MIN-10.
Heinrich Ludwig Rudolf Fuess (1838–1917) was one of the leading manufacturers of optical instruments in Germany during his time.
This stage represents an intermediate model between the small and full-size four-axis stages.
Four-axis intermediate stage with large base.
Full-size four-axis stage. The stage has the number 8786.
Rudolf Winkel was a German mechanic and entrepreneur who achieved particular success in microscope development and production. In 1857, he founded the company "R. Winkel Göttingen." In 1911, Carl Zeiss became the company's main shareholder.
The stage has the number 3178.
The instrument maker Ernst Leitz (1843–1920) arrived in Wetzlar in 1864 and joined the Optisches Institut. Trained as a maker of physical and chemical instruments with extensive experience in Swiss watchmaking, Leitz initially became a co-owner of the company and its sole owner in 1869.

The stage has the number 328909 and was produced around 1937.
The stage has the number 1707.
The stage has the number 1683.
In 1846, Carl Zeiss opened an optical workshop in Jena, obtaining a license to produce and sell mechanical and optical instruments. In 1875, Carl Zeiss and Ernst Karl Abbe jointly founded a company. Following the formation of the GDR, the state-owned enterprise VEB Carl Zeiss Jena was established.
The stage has the number 283249 and was produced in 1975.
The stage has the number 4342446
Rathenower Optische Werke (ROW) resulted from the merger of two optical companies: Emil Busch and Nitsche & Günther. In 1948, ROW became VEB Rathenower Optische Werke, a state-owned enterprise in the GDR. In 1966, ROW was merged with VEB Carl Zeiss Jena, but was separated again at the end of 1989.
The stage has the number 5950.
The enterprise was established in November 1931 as the Experimental Plant of Geophysical Instrument-Making, based on the production workshops of "Goslestochpribor" under the Supreme Council of the National Economy. In 1972, it became part of the Scientific and Production Association "Rudgeofizika," which focused on developing advanced geophysical technologies. After leaving the association, the plant was renamed FGUNPP "Geologorazvedka."
The device was developed by V. G. Feklichev for measuring the refractive indices of crystals using a rotating needle. It has the number 316 and was produced in 1972.
