| Abstract: | In this paper, a measuring method of convex lens foci in collimator is given. This method needs no expensive instrument and apparatus,and doesn't need to disassemble the collimator either,but it can measure the foci of the convex lens at the other end by only taking the narrow_gap at the one end of collimator as a "bridge". |
