Abstract

A method of reversibly separating an imaging assembly from an optical path in a laser surgical system includes generating an electromagnetic beam, propagating the electromagnetic beam from the beam source to a scanner along an optical path, the optical path comprising a first optical element that attenuates the electromagnetic beam, reversibly inserting a confocal bypass assembly into the optical path, diverting the electromagnetic beam along a diversion optical path around the first optical element, wherein the confocal bypass assembly automatically exits the optical path when a power loss occurs to one or more components of the system.
