Abstract
The utility model discloses a kind of burnt telecentric lens of length of image measurer, comprise camera lens part and mirror body, described camera lens part is fixedly connected with mirror body, described camera lens part includes the concave mirror setting gradually, convex mirror, little convex mirror and little concave mirror, described concave mirror, convex mirror, little convex mirror and little concave mirror outer ring are wound with screw thread, on described screw thread, screw in corresponding disk, described each disk holds mutually, described mirror body front end is provided with biconvex eyeglass, in described mirror body, be equipped with and be pressed into the lens set that light direction arranges, described lens set rear portion is provided with corresponding trim ring, the burnt telecentric lens of length of this image measurer is flexible, rational in infrastructure, and can be applicable to the less object of observation and overcome measure the error producing, and arbitrarily changes eyeglass simultaneously.
Description
Technical field
The utility model relates to a kind of burnt telecentric lens of length of image measurer.
Background technology
While being used for closely observing and measuring compared with wisp, require camera lens will have enough enlargement factors on the one hand, can observe the slight part of body surface, require again on the other hand image not occur distortion, traditional camera lens can be realized the function of large multiple, but the light that enters camera lens due to body surface reflection is radial pattern, when the distance of object and camera lens changes, chief ray can be inconsistent with the difference of distance, object just there will be change at the imaging size of video camera CCD target surface, when change scope is larger, image also there will be distortion, therefore the change of object and distance of camera lens can affect measurement result, there is measuring error.
General by exchanging distance or the anglec of rotation of step motor control camera lens in prior art, because this control mode is more limited to the rotation of camera lens especially translation, therefore the zoom of camera lens is also limited, cannot effectively meet the requirement to the large small workpiece of difference or different measuring accurate rate.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of flexible, rational in infrastructure, and can be applicable to the less object of observation and overcome measure the error producing, and arbitrarily changes the burnt telecentric lens of length of the image measurer of eyeglass simultaneously.
For addressing the above problem, the utility model adopts following technical scheme:
A kind of burnt telecentric lens of length of image measurer, comprise camera lens part and mirror body, described camera lens part is fixedly connected with mirror body, described camera lens part includes concave mirror, convex mirror, little convex mirror and the little concave mirror setting gradually, described concave mirror, convex mirror, little convex mirror and little concave mirror outer ring are wound with screw thread, on described screw thread, screw in corresponding disk, described each disk holds mutually, described mirror body front end is provided with biconvex eyeglass, in described mirror body, be equipped with and be pressed into the lens set that light direction arranges, described lens set rear portion is provided with corresponding trim ring.
As preferably, described camera lens part circle of position cylindricality arranges.
As preferably, described lens set is concave mirror lens set.
The beneficial effects of the utility model are: owing to being provided with camera lens part, can utilize the architectural feature of the mutual stack combinations of a plurality of eyeglasses, overcome the error of measurement, the less object of observation is also convenient in the setting of a plurality of camera lenses simultaneously, and owing to being provided with disk, simultaneously described each disk holds mutually, can utilize the architectural feature that holds and be threaded, make the replacing of eyeglass convenient, thereby reach the effect of focusing, more flexible.
Accompanying drawing explanation
Fig. 1 is the planimetric map of the burnt telecentric lens of length of a kind of image measurer of the utility model.
Embodiment
Consult shown in Fig. 1, a kind of burnt telecentric lens of length of image measurer, comprise camera lens part 1 and mirror body 2, described camera lens part 1 is fixedly connected with mirror body 2, described camera lens part 1 includes the concave mirror 3 setting gradually, convex mirror 4, little convex mirror 5 and little concave mirror 6, incident direction according to light sets gradually, can reach the effect of many times of amplifications, described concave mirror 3, convex mirror 4, little convex mirror 5 and little concave mirror 6 outer rings are wound with screw thread 7, on described screw thread 7, screw in corresponding disk 8, described each disk 8 holds mutually, the front and rear of disk 8 is provided with corresponding annular protrusion (not shown) and annular groove (not shown), structure by annular protrusion and annular groove holds fixing, when loading mirror, disk 8 is threaded with corresponding mirror, then hold and can reach simple stack fixed effect with other disk 8, described mirror body 2 front ends are provided with biconvex eyeglass 9, in described mirror body 2, be equipped with and be pressed into the lens set 10 that light direction arranges, described lens set 10 rear portions are provided with corresponding trim ring 11, trim ring 11 is pushed down lens set 10 and is fixed.
Described camera lens part 1 circle of position cylindricality arranges, and is convenient to precession and back-out.
Described lens set 10 is concave mirror lens set, matches reach the effect of amplifying focal length with the eyeglass of camera lens part.
The beneficial effects of the utility model are: owing to being provided with camera lens part, can utilize the architectural feature of the mutual stack combinations of a plurality of eyeglasses, overcome the error of measurement, the less object of observation is also convenient in the setting of a plurality of camera lenses simultaneously, and owing to being provided with disk, simultaneously described each disk holds mutually, can utilize the architectural feature that holds and be threaded, make the replacing of eyeglass convenient, thereby reach the effect of focusing, more flexible.
The above, be only embodiment of the present utility model, but protection domain of the present utility model is not limited to this, and any variation of expecting without creative work or replacement all should be encompassed in the new protection domain of this practicality and be as the criterion.
