in january 2005, the french company laster technologies was founded by a group of experts in optics and image processing at cnrs (centre national de la recherche scientifique). the company's patented enhancedview technology uses a unique optoelectronic device based on a semi-reflective diopter with a mathematically calculated curve enabling the reflection of a virtual collimated image directly into the wearer's field of view. the use of enhancedview technology, coupled with an oled micro-screen provides a 40 ° x 30 ° (h x v) field of vision with a resolution of 800 x 600 pixels or more. this is equivalent to viewing a floating screen of 90 cm diagonal at a distance of one meter. it is the result of an intensive collaborative development work with the institut d'optique and the university of paris-sud over several years.
