Abstract

A laser beam projector equipped with a CCD camera for taking a picture of a spot for treatment, thus permitting observation of the spot by sight. The laser beam projector has an annular projection formed around a circular hole made on the front of its casing, and a trapezoid heat sink is fitted in the circular hole with its base caught by the circumference of the annular projection. The annular projection has threads formed on its outer circumference. A tapered cap has a laser beam throwing aperture made on its top end. The tapered cap is screwed and fixed to the annular projection, and the tapered head is applied to the spot with the laser beam aperture closed with the skin. The heat sink has a through hole made at its center, and a magnifying lens is placed deep in the through hole, and is directed to the laser beam throwing aperture. The CCD camera is placed behind the magnifying lens with its focal plan aligned with the lens. Another through hole is made above the through hole at an oblique angle relative to the center line of the heat sink. A spherical lens is fitted in the open end of the oblique through hole, and the spherical lens is directed at the laser beam throwing aperture. A laser diode is placed behind the spherical lens. A plurality of through holes are made around the center through hole, and a high-intensity, white light emitting diode is inserted in each through hole.
