[0012] The focusing device 20 may sequentially provide a collimating lens and a focusing lens, and the focusing device 20 is opposite to the lens 200 to be tested, and passes through the light source device 10 with a certain length. The first light-conducting element 61 is connected, for example, to an optical fiber, and the first light-conducting element 61 conducts a light beam emitted from the light source device 10 to the focusing device 20, and becomes a parallel beam through the collimating lens.
