For achieving the above object, the technical scheme that the utility model is taked is: a kind of CCD translation interface camera lens, comprise lens barrel, and in lens barrel, be provided with image acquisition light path; On lens barrel, export corresponding one end with image acquisition light path and be provided with CCD connecting portion, the other end is provided with eyepiece connecting portion; In image acquisition light path, be provided with lens group; Lens barrel is provided with focusing knob;
Lens group is comprised of lens orientation frame and the eyeglass being fixed in lens orientation frame; Eyeglass is comprised of a plano-convex lens and the concave-convex lens arranged along light path bearing of trend; The plane of plano-convex lens is relative with the convex surface of concave-convex lens;
Focusing knob lower end sidepiece is provided with biasing post, and lens orientation frame is provided with post groove; Focusing knob connects lens barrel wall, and biasing post stretches in post groove, so that focusing knob is when rotate, lens orientation frame rotates and moves in image acquisition light path with biasing post.
The utility model, when application, can be connected by modes such as screw threads CCD connecting portion with CCD device, object lens connecting portion is connected with microscopical objective lens; When needs are focused, only need can change the position of lens group in image acquisition light path by rotation focusing knob, thereby change the distance between lens group and CCD target surface and object lens, realize the object of Image Zooming.
Further, in order to make focusing knob time can not rotate and cause lens group to move without operation, in the utility model, on lens barrel, be also provided with holding screw; Holding screw is axially axially mutual vertical with focusing knob, and one end is positioned at outside lens barrel wall, and the other end can butt focusing knob.A kind of preferred embodiment of holding screw can be: holding screw is comprised of screw body, stage clip and jacking block, and attachment screw body one end, stage clip one end connects jacking block; Jacking block and focusing knob butt.Under the effect of stage clip, jacking block can be all the time and focusing knob butt, thus the location of realizing focusing knob; Holding screw also can directly make its top press focusing knob by screwing after each focus adjustment in addition, realizes the location of focusing knob.
In order to protect the light path in converting interface camera lens clean and tidy, on the CCD connecting portion of lens barrel and eyepiece connecting portion, be all provided with detachable protective lid.When needs connect use, over cap is pulled down.
In order further to guarantee that the imaging definition of lens group, the eyeglass in len group are not subject to pollution or the wearing and tearing of dust particle etc., the equal coated with protective film in the two sides of plano-convex lens and concave-convex lens in the utility model.Diaphragm can adopt plated film form, can be existing magnesium fluoride MF
2film.
Accompanying drawing explanation
