An optical object distance simulation device for reducing total optical path includes: a lens, an achromatic lens set, a first image lens, and a second image lens. The achromatic lens set disposes beside one side of the lens, the first image lens disposes beside one side of the achromatic lens set, and the second image lens disposes beside one side of the first image lens. The achromatic lens set is composed of a first lens and a second lens. The first lens is a double-concave lens. The second lens is a double-convex lens. One concave face of the double-concave tightly contacts with one convex face of the double-convex lens. Therefore, the lens, the achromatic lens set, the first image lens, and the second image lens match with each other in order to simulate real object distance for reducing an object distance between a test camera lens and a corresponding chart.

An apparatus for measuring the static parameters of integrated circuit is disclosed. When the apparatus is operated, the output mode is determined automatically according to the load of the integrated circuit. When the apparatus is operated in voltage output mode, the apparatus automatically limits the current. When the apparatus is operated at current output mode, the apparatus automatically limits the voltage. Therefore, the operation voltage and the operation current are stabilized. When the tested integrated circuit fails, the apparatus of the present invention can protect itself according to the stable operation voltage and operation current, and doesn't damage the tested integrated circuit.
