ABSTRACT:
A microscope attachment assembly is provided for pivotably mounting a surgical laser to a microscope. A micromanipulator housing is adapted to swing away to an off-axis position to facilitate exchanging the objective lens of the microscope. The spot size of the laser is controlled by shifting the position of a field lens included in a field lens assembly which is shifted along the laser beam by a stepper motor. By toggling a cut/coagulate switch, the field lens is moved between a presetable cut-mode position and a presetable coagulate-mode position.
