Title
(EN) IMAGING DEVICE FOR OPHTHALMIC LASER SYSTEM USING OFF-AXIS MINIATURE CAMERA
(FR) DISPOSITIF D'IMAGERIE POUR SYSTÈME LASER OPHTALMIQUE UTILISANT UNE CAMÉRA MINIATURE HORS AXE
Abstract
(EN)
An imaging system for an ophthalmic laser system includes a prism cone made of a transparent optical material and disposed downstream of the focusing objective lens of the ophthalmic laser system, the prism cone having an upper surface, a lower surface parallel to the upper surface, a tapered side surface between the upper and lower surfaces, and a beveled surface formed at an upper edge of the prism cone and intersecting the upper surface and the side surface, and a camera disposed adjacent to the prism cone and facing the beveled surface. The camera is disposed to directly receive light that enters the lower surface of the prism cone and exits the beveled surface without having been reflected by any surface.
(FR)
L'invention concerne un système d'imagerie pour un système laser ophtalmique qui comprend un prisme conique constitué d'un matériau optique transparent et disposé en aval de la lentille d'objectif de mise au point du système laser ophtalmique, le prisme conique ayant une surface supérieure, une surface inférieure parallèle à la surface supérieure, une surface latérale conique entre les surfaces supérieure et inférieure, et une surface biseautée formée au niveau d'une arête supérieure du prisme conique et croisant la surface supérieure et la surface latérale, et une caméra disposée adjacente au prisme conique et faisant face à la surface biseautée. La caméra est disposée pour recevoir directement la lumière qui entre dans la surface inférieure du prisme conique et qui sort de la surface biseautée sans avoir été réfléchie par une quelconque surface.
