Handpiece for producing highly collimated laser beam for dermatological procedures |
摘要 |
A handpiece for use in delivering the output beam of a laser to the surface of a patient's skin for performing a dermatological procedure. In a first and second embodiment of the present invention, the handpiece provides a highly collimated beam of a fixed, non-variable spot size which is largely insensitive to movement of the handpiece over a range of working positions. In a third embodiment the handpiece provides a highly collimated and well defined focused laser spot of variable size where for a selected spot size, the size is largely insensitive to movement of the handpiece over a range of working positions. In all of the embodiments, the highly collimated laser beam permits the surgeon performing the procedure to move the handpiece over a range of positions without significantly defocusing or altering the spot size of the beam.
