Abstract:
An adaptor for attachment to a laser apparatus and to a microscope for directing at least one laser beam from the laser apparatus onto an object in a working plane as viewed through the microscope, the adaptor comprising:an optical system in alignment with the laser apparatus, said optical system comprising:a reflector system for expanding said at least one laser beam from the laser apparatus, said reflector system including;a planar reflector including oppositely disposed first and second reflecting surfaces and also including a substantially centrally positioned opening extending through said planar reflector; anda first concave mirror disposed laterally with respect to said first reflecting surface of said planar reflector to receive said at least one laser beam reflected from said first surface and to focus said at least one laser beam at a focal plane at said opening;a focusing mirror aligned with said reflector system, said focusing mirror including a second concave mirror disposed laterally with respect to said second reflecting surface of said planar reflector for focusing said at least one laser beam passing through said opening;a manipulable mirror located between the optical system and the working plane, wherein the manipulable mirror is selectively manipulable to direct said at least one laser beam to any desired location in the working plane;a focusser coupled to said optical system, said focusser being capable of selectively focusing and defocusing said at least one laser beam, said focusser comprising,a working distance adjustment ring and a defocus ring both coupled to the second concave mirror; andmeans responsive to the movement of said focusser for causing said second concave mirror to move relative to said planar reflector.
