Summary of the invention
The purpose of this utility model provides a kind of 6.0mm to 60.0mm zoom lens, and this camera lens not only helps realizing the zoom of camera lens in 6.0mm to 60.0mm scope, and simple to operate, and result of use is good.
The purpose of this utility model is achieved in that this 6.0mm to 60.0mm zoom lens, comprise main tube and be located at inboard focusing lens chip module, aperture adjusting part and the focusing lens assembly of main tube successively along the light incident direction, described focusing lens chip module is provided with six focusing lenss, described focusing lens assembly comprises moving group that is fixed in quiet group in the aperture adjusting part rear side master tube and is located at quiet group of rear side, be respectively equipped with three condenser lenses on described quiet group and the moving group, described moving group and focusing lens chip module can move axially along main tube.
Distinguishing feature of the present utility model is quiet group and the reasonable setting and the cooperating of moving group by focusing lens chip module and focusing lens assembly, realized the zooming range of 6.0mm to 60.0mm, can be applicable to the multiple occasion that has vista shot to need, satisfied certain market demand.
In addition, this lens construction is reasonable, and is simple to operate, and simple installation has the actual feasibility of applying.
