Patent ID: 8303125

Claim:
A focus apparatus, comprising: a light apparatus operable to generate light and emit the 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 object lens and second object lens, and wherein 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; an adapter operable to connect the light apparatus and the optical apparatus; wherein the light apparatus comprises a heat sink and a scatter plate, wherein the light generated by the light apparatus passes through the heat sink, the scatter plate, the adapter, the partial reflector, and the second object lens to project the light onto the surface of the object, wherein the heat sink transfers thermal energy generated by the light apparatus to the air of the surrounding environment to make a wavelength of the light fall in an allowable wavelength range, and wherein the scatter plate scatters the light to make the light propagate uniformly.
