On-site optical risk assessment

Sources of artificial light such as LEDs (non-coherent) and lasers (coherent), as well as the systems that integrate them, can, under certain conditions, cause...

Characterization of materials for optics

Illumination, detection and visualization systems integrate optical components manufactured and treated from different (optics) materials. Indeed, these materials transmit, reflect, absorb, diffuse optical radiation...

Radiometric measurements in the UV

Ultraviolet (UV) radiation is included in the part of the light spectrum ranging from 200nm to 380nm. They are more energetic than the radiation...

Characterization of phosphorescent devices

Phosphorescent materials have the particularity of emitting light during a period of time which depends on their nature and duration of exposure to light...

Benchmark optical flickering of LED lamps

Discover the state of the art of optical flickering performance of commercialized LED lamps. Abstract : Optical flickering refers to the glittering, sparkling or even instability...

Photobiological risk evaluation EN62471

Photobiological risk assessment (EN62471 and IEC TR 62778) is one of the mandatory provisions imposed by the European Commission to ensure the safety of...

Characterization of displays and luminous surfaces

On entend par "écran" toute surface lumineuses telle que les enseignes lumineuses, claviers rétro-éclairés, pictogrammes, boutons lumineux, marquages phosphorescents, signalétique.. Ces surfaces lumineuses présentent des...
