Our partners benefit from our optical design and imaging and illumination system prototyping abilities. Our know-how focuses on freeform lens design, optomechanical assemblies, visual ergonomics evaluation and performance tests. We have recognized design and simulation tools as well as the metrology capabilities required to apply our expertise at all stages of product realization.
With new technological advances in imaging and illumination such as LEDs, freeform lenses and the study of human factors related to lighting, there are more and more new solutions to technical and commercial challenges.
We have developed a proprietary simulation platform that is coupled with commercial software. Using this platform, we can optimize freeform mirror and lens design. We follow an approach that aims to optimize performance while taking into account tolerances and manufacturing costs. We have also built up prototyping expertise for experimentally validating digital models. Following the design stages, we are able to print lenses and mirrors using fast 3D printing and to validate a technical concept or marketing approach at a reasonable cost. We can also produce high-precision machined prototypes thanks to our laboratory equipped with a diamond turning lathe and our optomechanical prototyping team.
We have set up a photometric laboratory. We specialize in characterization of light sources and measurement of the optical properties of surfaces and materials. We operate two near-field goniometers that we use to measure and understand the behaviour of optical sources and elements to refine the design and prototype models. We also have the facilities and expertise for measuring the BRDF of surfaces and the BTDF of translucent materials.
Human Factors – Visual Ergonomics
Our team performs computer-assisted simulations to reproduce the photometric conditions (luminance, illuminance and chromatic coordinates) of various specialized control stations such as cockpits or heavy machinery cabins. We also perform visual ergonomics analyses on digital results and directly on the physical stations to ensure that the natural and artificial lighting environment is comfortable and meets visual ergonomics criteria. We are currently building a modular laboratory for studying the visual ergonomics of specialized control stations. The laboratory will be made up of a modular lighting platform incorporated into an immersion chamber. The behaviour of study subjects will be digitized using a passive movement capture setup and eye-tracking glasses.
