Revised Chinese Manual (November 89) V. Description of Invention (7 ) Turn to "2" and follow the objective lens 2 2 and use the infinite correction objective lens 3 4. The printed circuit board 14 is substantially placed on the focal plane of the infinity-corrected objective lens 34 to form a substantially infinite image ^ The image formed by the infinity-corrected objective lens 34 can be viewed directly by the camera assembly 18, but viewing optics must be used 1 9. In the specific embodiment of FIG. 2B, since there is no relay objective lens 22, the microscope 16 needs to be placed far closer to the printed circuit board 14 than the specific embodiment of FIG. 2A. Reference is now made to Figs. 3A and 3B 'which are simplified optical illustrations of the specific embodiment of Figs. 2A and 2B, respectively. Referring to FIG. 3A, it can be seen that the focal point of the relay objective lens 2 2 is F 1, and it is preferably separated from the printed circuit board 4 by a distance of about 148 mm. The eyepiece 24 is preferably spaced 187.7 mm from the relay objective lens 22, and its focus indication is F2. Note that the relay objective 2 2 is located at a distance of 2 X FI from the viewing plane 2 of the printed circuit board. 4 The focus F 2 of the eyepiece 2 4 adjacent to the relay objective 2 2 is located at 22 2 XF from the relay objective. i distance. It should be understood that the relay objective lens 22 may be replaced with any suitable objective lens ‘the objective lens is operable to form an intermediate image near the focal plane f 2 of the eyepiece 24’ and whether such intermediate image may be magnified. Figure 3A also illustrates the viewing optics 19 and the CCD focal plane 28 of the camera assembly 18 (Figure 2A). The focal length of the viewing optical device 19 is denoted as F3. The focal length ratio of the viewing optics 19 and the eyepiece 24 is preferably 2-3 times larger than the focal plane 28. Referring to FIG. 3B, it can be seen that the infinity-corrected objective lens 3 4 has its focus shown at ρ · 4, and is preferably separated from the printed circuit board 1 4 by the focal length f 4 distance = FIG. 3 B also illustrates the viewing optics 3 of the camera assembly 丨 8 as an example. 6 and CCD focal plane 3 8.
