Embodiment
By describing technology contents of the present utility model, structural attitude in detail, realized purpose and effect, below in conjunction with embodiment and cooperate that accompanying drawing is detailed to give explanation.
The first embodiment
See also Fig. 1, the optical lens of present embodiment comprises lens barrel 1 and optical mirror slip (not shown), is provided with through hole 2 in the lens barrel 1, and optical mirror slip is placed in this through hole 2.Lens barrel 1 rear end face is provided with and is two staggered optical filters of cruciform and puts groove 3, two optical filters and put groove 3 and be rectangle, and optical filter is put groove 3 and is used for the optical filter of accommodating adapted shape and makes the optical filter that is placed therein cover through hole 2.
Because optical filter is put groove 3 and is all covered through hole 2 for the fixed optics eyeglass, therefore, no matter at which optical filter to put in the groove 3 and place optical filter, optical filter all can effectively play the effect of optical filtering.
Two optical filters are put groove and namely be can be used for placing two kinds of different optical filters, can correspondingly place more optical filter when the optical filter that is provided with three even greater number is put groove, can arrange according to actual demand and lens barrel sectional area.
The second embodiment
See also Fig. 2, in the present embodiment, optical lens comprises lens barrel 1 and optical mirror slip (not shown) equally, be provided with the through hole 2 for accommodating described optical mirror slip in the lens barrel 1, lens barrel 1 rear end face except be formed with embodiment one in identical two in one plane be the staggered optical filter of cruciform and put the groove 3, also have one and be lower than this two optical filter and put the optical filter that is square of groove 3 and put groove 3, this square optical filter is put groove 3 and other two optical filters and is put that groove 3 is whole to consist of step troughs.Three optical filters are put the optical filter covering through hole 2 that groove 3 all can be placed therein.
On two different levels planes, consist of altogether three optical filters in the present embodiment and put groove, can place like this three kinds of different optical filters.The cross section structure of each layer plane of step trough all can be made variation, for example all form a plurality of staggered optical filters on bottom (being that box filter is put plane, groove place in the present embodiment) and upper strata and put groove or all only form an optical filter and put groove, wherein optical filter is put groove and can be rectangle, square or circular.In addition, can also have more than two-layer ladder.
