Abstract

La présente invention concerne un article en verre feuilleté. L'article a une couche centrale, une première couche de revêtement et une deuxième couche de revêtement. La couche centrale a un coefficient de dilatation thermique (CTE) central. La couche centrale est disposée entre la première couche de revêtement et la seconde couche de revêtement. Chacune de la première et de la seconde couche de revêtement a un CTE de plaquage. Le CTE de plaquage est inférieur au CTE central, de telle sorte que chacune de la première et de la seconde couche de plaquage est soumise à une contrainte en compression, tandis que la couche centrale est soumise à une contrainte en traction. L'article en verre feuilleté est sensiblement transparent aux infrarouges et absorbe sensiblement la lumière visible. Dans des modes de réalisation, l'article en verre stratifié est fabriqué par un procédé d'étirage par fusion et peut être utilisé en tant que couvercle LiDAR pour un capteur LiDAR.
