History
This company was founded in 1966 by two companies : CGE (Compagnie Generale d'Électricité becoming
Alcatel-
Alsthom) and
Saint-Gobain. The aim was to exploit industrially and commercially the work of laboratories working on

sources and laser equipment.
In 1983, it became CILAS-
Alcatel. In 1985, it was absorbed by two companies of optics : SORO Electro-Optics and BBT (Barbier Bernard and Turenne).
Alcatel withdraws its laser activities in 1989, resulting in a change of ownership. In early 1990, the capital is divided between three companies,
CEA Industries (now

), SAT and Unilaser Holding (Aerospace Group). CILAS-Alcatel becomes CILAS.
Meanwhile, from late 1989, the Unilaser group also acquired the Optronics Division of Alcatel Marcoussis laboratories and named it Laserdot. Unilaser now gather Quantel, LISA, CILAS and Laserdot.
From this moment, Laserdot and CILAS collaborate on joint projects. Laserdot is more oriented toward research and development whereas CILAS toward industrialization and production.
In 1994, SAT withdraws CILAS' capital and shares of the two remaining shareholders passed to 57% for Unilaser and 43% for CEA Industry. On September 1, 1995, CILAS and Laserdot are merged into a single entity which retains the name CILAS.
Defence and security
Cilas develops and manufactures different products in the field of defence and security. It offers laser designators,
counter-snipers optical sight systems detectors, rangefinders, airborne laser sources and shipborne helicopters landing aids.
