GESTIONE SILO: Customized, Precision Opto-Mechanical Components – Since 1976

GESTIONE SILO is an Italian company specialized in custom precision optics and optomechanical assembly for Space, Defense, Biomedical, Research and Industrial applications. The company was founded in 1950 and after many technical improvements, today is a leader in the production of custom optics. The headquarter is located in Scandicci near Florence, with 1200 square meters and about 35 employees.

Since its foundation GESTIONE SILO has been growing in the optomechanical and optical fields in Italy, finding approval and a reference market. The Company’s mission is to create a customer-oriented system that guarantees solutions tailored to the respective customer requirements of different sectors. To achieve such results, GESTIONE SILO aims at improving conventional technology and developing innovative technology, matching know-how, and research.

Design and assembly of fully custom optomechanical systems: lenses, eyepieces, relay lenses, collimators

Starting from an idea or specific requirements, GESTIONE SILO is capable of supporting the customer in designing and integrating optomechanical systems and complex instruments, such as telescopes, microscopes, spectrometers, and earth vision systems.

The Company is equipped with a Clean Room, for the integration of instruments in a controlled environment according to the ISO5 class, as well as a large climatic chamber to test in the temperatures range of (-40°C, +180°C), thermal shocks, and conditions of high humidity.
