Publication number: 20230201037Abstract: An ophthalmic laser system for generating a first beam at a first wavelength on a first beam path and a second beam at a second wavelength on a second beam path, and directing optics to selectively direct the first beam or the second beam to a treatment beam path. The ophthalmic laser system incorporates a reflex coaxial illuminator comprising a reflex mirror movable on an axis from a position out of the treatment beam path to a position in the treatment beam path to direct illumination into an illumination path coaxial with the treatment beam path. The reflex mirror is adapted to transmit a beam that follows the second beam path.Type: ApplicationFiled: March 3, 2023Publication date: June 29, 2023Inventors: Bradley Barrett, David Haarhoff, Timothy Dixon
