Abstract:
1. A focus apparatus, comprising: a spectroscope; a first illuminator operable to emit light onto an object; an optical apparatus operable to generate an image of the object, wherein the optical apparatus comprises a first object lens, a second object lens, and a partial reflector located between the first and second object lens, and the partial reflector is not parallel to the second object lens; an image capture apparatus operable to receive the image of the object from the optical apparatus, and convert the image into electronic signals; a patterned light apparatus operable to generate patterned light, wherein the patterned light apparatus is perpendicularly mounted to the spectroscope, wherein the patterned light apparatus comprises a second shell, a second illuminator, a first magnification adjuster, and a pattern slide, patterns are formed on a surface of the pattern slide, and the second illuminator is located at a distal end of the second shell and opposite to the spectroscope; a coaxial light apparatus operable to generate coaxial light, wherein the coaxial light apparatus is perpendicularly mounted to the spectroscope, and is perpendicular to the patterned light apparatus; and the spectroscope operable to refract the patterned light emitted from the patterned light apparatus and the coaxial light emitted from the coaxial light apparatus to the optical apparatus.
