Abstract
The utility model relates to a kind of micrometer lens having a scaling function, namely a kind if common optical experiment digitalization observation matching lens having a scaling function. The lens includes an object lens, an eye lens and a coupling sleeve, characterized in that a graduation board made of transparent material is arranged between the object lens and the eye lens. The graduation board is a transparent board with metric graduation marks on its surface. Thereby, it is possible to scale directly by using the graduation board in the object lens without extra scaling devices, scaling operation is simple and convenient, saves time and trouble, but also the utility model is economical and practical, and has high performance-price ratio.
Description
Technical field
The utility model relates to a kind of micrometer camera lens, promptly a kind of ordinary optical experiment digital observation coupling camera lens; Particularly a kind of micrometer camera lens that the calibration function is arranged promptly has the ordinary optical experiment digital observation of calibration function to mate camera lens.
Background technology
In ordinary optical experiment, the measurement of millimeter magnitude yardsticks such as the observation that often relates to striped and fringe spacing.In measuring process, key is the accurate measurement of fringe spacing.Digital observation device commonly used has the area array CCD of linear array, area array CCD and the band camera lens of not being with camera lens in the ordinary optical experiment at present, and the former will test under the environment of darkroom usually, and requires optical phenomena can transfer to (only being suitable for part tests) on the CCD face; The latter's micrometer camera lens, promptly existing ordinary optical experiment digital observation coupling camera lens needs can do relative measurement to the object of observation focusing, then needs by the calibration in advance of extra calibration device if will accurately measure, and experimentation is loaded down with trivial details, and is time-consuming bothersome.
Summary of the invention
At above problem, the purpose of this utility model provides a kind of micrometer camera lens that the calibration function is arranged convenient, that save time and save trouble of calibrating.
A kind of micrometer camera lens that the calibration function is arranged comprises object lens, eyepiece and coupling sleeve, it is characterized in that: be provided with the scale graticule made from transparent material between object lens and eyepiece.The described scale graticule made from transparent material is the transparent panel that the fingerboard face is provided with the tolerance scale mark.
The utility model is because of being provided with the scale graticule made from transparent material between object lens and eyepiece, so, can in camera lens, utilize the scale graticule directly to calibrate, need not be by extra calibration device, not only calibrate simple and convenient, save time and save trouble, and economical and practical, be the high micrometer camera lens of a kind of cost performance.

Fig. 1 is a kind of structural representation of the present utility model,
Fig. 2 is a kind of scale graticule structural representation of the present utility model,
Fig. 3 is an another kind of scale graticule structural representation of the present utility model.
Among the figure: object lens 1, scale graticule 2, eyepiece 3, coupling sleeve 4, cross mark 5, tolerance scale mark 6.
Embodiment
Describe in detail below in conjunction with drawings and Examples:
Fig. 1 is a kind of micrometer camera lens that the calibration function is arranged of the present utility model, and the ordinary optical experiment digital observation coupling camera lens of calibration function is promptly arranged.Mainly comprise object lens 1, eyepiece 3 and coupling sleeve 4, it is characterized in that: between object lens 1 and eyepiece 3, be provided with the scale graticule made from transparent material 2.
Fig. 2 and Fig. 3 are two kinds of scale graticules of the present utility model.The central authorities of two kinds of scale graticules 2 all are provided with cross mark 5, so that easily and intuitively object of observation is positioned observation.
For the ease of directly measuring the yardstick of object of observation, object lens 1 enlargement factor preferably is set to one times, and promptly object lens 1 are the object lens of one times of enlargement factor.
For the ease of calibrating simultaneously and measuring, the tolerance scale mark 6 among Fig. 2 is arranged on the horizontal line of cross mark 5, and promptly scale graticule 2 central authorities in Fig. 2 are provided with cross mark 5, and tolerance scale mark 6 is arranged on the horizontal line of cross mark 5.
For the ease of vertical scale and the breadth wise dimension of measuring object of observation simultaneously, anyhow all be provided with tolerance scale mark 6 on the line of the cross mark 5 in Fig. 3, be that scale graticule 2 central authorities among Fig. 3 are provided with cross mark 5, and on the line anyhow of cross mark 5, all be provided with tolerance scale mark 6.
