Title
(EN) OPTHALMIC INSTRUMENT EYEPIECE EXTENDER
(FR) PROLONGATEUR D'OCULAIRE POUR INSTRUMENT OPHTALMIQUE
Abstract
(EN) The disclosure relates to an eyepiece extender for an ophthalmic microscope, such as a slit lamp microscope. The eyepiece extender comprises certain lens designs and arrangements and provides ergonomic improvement to a user of the ophthalmic microscope and accommodates different magnifications, such as high and low magnifications, while preserving image fidelity for each magnification such that the image is essentially distortion free and color corrected in each magnification instance.
(FR) L'invention concerne un prolongateur d'oculaire pour un microscope ophtalmique, tel qu'un microscope à lampe à fente. Le prolongateur d'oculaire comprend certaines conceptions et agencements de lentilles et fournit une amélioration ergonomique à un utilisateur du microscope ophtalmique et reçoit différents grossissements, tels que des grossissements élevés et faibles, tout en préservant la fidélité d'image pour chaque grossissement de telle sorte que l'image est sensiblement exempte de distorsion et corrigée en couleur dans chaque instance de grossissement.
