Engineering & innovation

Optics and detection


The optics and detection centre of expertise was set up in January 2007 and engages in four main areas of activity:
  • Technical assistance on integrated team projects carried out on our clients’ premises,
  • Full fixed package studies carried out at our design and engineering department based on our own Sophia Antipolis, Cannes, Paris and Toulouse sites.
  • Research & development on innovative projects working as part of a consortium
  • Training and education

The enormous diversity of our engineers’ skills offers vital expertise during all of the phases involved in building an instrument, simultaneously combining optics, optoelectronics, electronics, materials and mechanical and thermal engineering. Our main areas of application are the Space industry, Defence, Energy, Micro-lithography, Observation, Photography and Projection, LED lighting and New Energies such as Solar Power.

Our team of engineers and doctors are currently working to make the Optics Centre even more dynamic and we have been gratified that, amongst others, THALES ALENIA SPACE, the CNES (Centre National d’Études Spatiales – National Centre for Space Studies), SAGEM DEFENCE SÉCURITÉ, THALES ANGENIEUX, NEXTER, VINCI CONSTRUCTION and the AUCHAN GROUP all see us as a trusted partner.

The Centre’s structure thus means that we can offer full services from the delivery of instruments and design studies which we handle on our own premises right through to the implementation phases carried out on our clients’ premises, also including the selection of suppliers, cost analysis and market studies, grouped together under three main headings:
  • Instrumentation and optical engineering;
  • Integrated engineering and optical tests on instruments or subassemblies;
  • Carrying out of optical benchmarking and the exploitation of existing optical resources.

Instrumentation and optical engineering


This expertise covers the areas of optical design studies, stray light, radiometry and test predictions.

The optical design activities, carried out using CODEV and ZEMAX software, mainly relate to:
  • the design, modelling and optimisation of optical systems (or instruments) taking their industrial feasibility into account;
  • optical analysis;
  • full optical tolerancing;
  • the EUV, UV, DUV, VIS, NIR and IR spectral bands.

Studies of stray light, carried out using ASAP and ZEMAX software, include:
  • full instrument modelling (optical components, mechanics, detection, etc.);
  • the VIS, IR and IRT spectral bands;
  • deciding upon diffusion models;
  • deciding upon properties for paints and coatings;
  • the mechanical dimensioning of baffles;
  • the modelling of stray light (ghost images, diffused light).

The radiometry and test prediction activities, carried out using ASAP and ZEMAX software, include:
  • modelling of radiometric performances;
  • studying the sensitivity of a radiometric performance;
  • simulating the development of an illumination;
  • an analysis of the energy response according to the spectrum and the angle of incidence.

Integrated engineering and optical tests on instruments or subassemblies


Integrated engineering activities and optical tests are carried out either as Technical Assistance or on our premises and relate to:
  • the drawing up of the test plan
  • deciding upon the ground resources required for the purposes of validating the performances
  • the drawing up of the test procedure
  • the sequence of events for the performance test
  • the characterisation of the instrument
  • the acceptance of the ground resources
  • the development of an acquisition interface including signal and image processing

Carrying out of optical benchmarking tests or exploitation of existing optical resources.


This expertise covers the area of optical test benches design and construction. For instance, it includes:

  • the drawing up and implementation of tests on the hardware provided
  • the management of suppliers
  • the measurements
  • the technical management (calibration, tracking of faults, etc.) of the equipment

Sample projects:› Study of the risks of aircraft crew being dazzled during the approach phase › Analysis of stray light and mechanical dimensioning for SPICA (Space Sector)› Design study for an LRA (Laser Reflector Array)
› Design, optimisation and tolerancing of HNA
