Patent number: 10555674Abstract: A confocal microscope having a scanning head in the form of a hand piece (102) which may be placed at selected locations on the body of a patient. A laser beam is scanned in orthogonal (horizontal and vertical) directions by scanners (128, 130) which drive scan mirrors (128a, 130a), which are closely adjacent to each other. The optics include an objective lens (138) and a single telescope lens (132, 134). The telescope provides sufficient magnification to overfill the entrance pupil of the objective lens (138) over the entire scan angle produced by the scan mirrors (128a, 130a).
