), 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 reteins the name CILAS.

Defence and security

Cilas develops and manufactures differents products in the field of defence and security. It offers laser designators, counter-snipers optical sight systems detectors, rangefinders, airborne laser sources ans shipborne helicopters landing aids.

Optics detector :
The SLD 500 laser surveillance system and sniper detector is a reliable tool for surveillance of sensitive areas and critical infrastructures protection. The system can detect and locate any kind of optical sight systems: optical scopes used by snipers or optronic sight systems. Not only is it capable of accurately localizing a threat, the system can also perform clear target identification using a high definition daylight camera or an infrared camera for night vision.

Laser designator :
The DHY 307 ground laser target designator belongs to the Modular Illuminating Range Finders (TIM) family developed by CILAS.
Intended for use by small ground units, it provides precision guidance for any missile, bomb or shell fitted with final laser guidance targeting an individual tactical objective.

Particle size analysis

Over 30 years ago, CILAS developed the world's first diffraction laser particle size analyzer for industrial applications. Since then, CILAS has been the market leader in product innovation; constantly striving to make their particle size analyzer easier to use, more reliable and flexible.
CILAS' state of the art laser particle size analyzer include features such as their patented short optical branch, intuitive software interface and a 2 in 1 design which effortlessly integrates wet and dry modes in the same system.
CILAS particle size analyzer works on determination and on control of the particle size in powder matter, in suspension or in emulsion which meet the needs of many and various fields like cement, ceramics, manufacturing industries, pharmaceuticals, cosmetics, biology, food or environmental industries.

Adaptive optics

Image has become an important tool for communication and scientific knowledge. When passing through distorting and turbulent media, Light waves and therefore images are distorted and blurred.
Since several years, the adaptive optic has become an essential component for Wave Front Correction, and has found numerous applications in astronomy, military observation, correction of scientific and industrial laser beams, and in medical imaging, especially in ophthalmology.

An Adaptive Optics system is a device which corrects, in real time, perturbed optical wavefronts. It is composed of:
An analyzer which measures the wave deformation.
A deformable mirror which corrects the wavefront.
A computer which drives the mirror with informations coming from the analyzer.
Deformable mirror MONO63 for high power laser Deformable mirror SAM416 DM 4.5 for Gemini Prototype of the future M4 deformable mirror for E-ELT




Optical ceramics

CILAS develops transparent ceramics that are usable as optical components. These top-quality materials, which have an excellent level of resistance and transparency, are fabricated using new synthesis techniques.

CILAS optical ceramics are the fruit of research that has been conducted by the Limoges Ceramic Processes and Surface Treatment Sciences Laboratory (SPCTS), a Joint Research Unit federating the French National Centre for Scientific Research (CNRS) and the local university, for some ten years. The SPCTS has developed a process to fabricate transparent ceramics, known as “YAG” (due to the name of the components: Yttrium and Aluminium Garnet). The feasibility of this operation was proven in cooperation with the Solids Modelling, Properties and Structures laboratory at the prestigious Ecole Centrale in Paris.

This transparent ceramic production activity is also the fruit of a partnership between CILAS, Rhodia Electronics & Catalysis and the European Centre of Ceramics within the framework of the Ceramoptic project. This project is backed by the French Minister for Industry, the Limousin region and the City of Limoges.

Nanotechnology

The term nanotechnologies refers to all theories and techniques used to produce and handle minuscule objects equal in size to one billionth of a metre (i.e. a nanometre). This technology requires very high precision tools to visualise, detect and analyse activities on such a small scale.

The nanotechnologies sector is flourishing, with nanotechnology company turnover
growing 100 times quicker than information technology majors.

In this domain, CILAS coordinates the European project Saphir for the safe, integrated
and controlled production of nanostructured products.

Recently, CILAS has developed a new product : the Nanoparticle aerosol monitor - SafeAir.
