Abstract

A protective film removal device has a first removal station for releasing a protective film from an optical lens first surface, a lens holder which has an imaginary central axis, at least one fluid nozzle having a nozzle exit duct, and a rotary mounting between the lens holder and the fluid nozzle(s). The rotary mounting is configured such that a relative movement about the central axis is able to be carried out by the fluid nozzle(s), wherein the nozzle exit duct of the fluid nozzle(s) is in each case oriented inwards. A lifting device between the lens holder and the fluid nozzle(s) is configured in such that a relative movement in relation to the lens holder, said relative movement being oriented along the central axis, is able to be carried out by the fluid nozzle(s). A method for releasing a protective film from a lens surface is also disclosed.
