Abstract
The utility model relates to a visual field switching structure of a reflection-type central measuring instrument, which mainly comprises an object lens, an ocular lens and a CCD monitor; the central measuring instrument is internally provided with a reflecting mirror which is arranged on a reflecting mirror base; the object lens is connected with a prism base by a connecting lens barrel; the position of the reflecting mirror corresponds to a prism on the prism base; the ocular lens is fixed on the central measuring instrument by a connecting sheath; the CCD monitor is connected with the reflecting mirror base by a clamping ring of the connecting sheath. The visual field switching structure has the advantages that: the reflecting mirror is inserted in a switching light path of a light-splitting prism, a crosshair partition target is imaged on the surface of the CCD surface when the reflecting mirror is cut in and on a partition board of the ocular lens when the reflecting mirror is moved out, thereby achieving different effects of different visual filed switching and causing one instrument to have the characteristics of vision and CCD monitoring simultaneously. The visual field switching structure utilizes a vision system when finding a target, has the characteristic of large visual field and is switched to the monitor during a centering operation, thus being capable of relieving visual fatigue.
Description
Technical field
The utility model relates generally to optical instrument field, mainly is that visualization and the CCD in the somascope of a kind of center observes the structure of switching.
Background technology
Center instrument is the instrument that is used for checking optical lens off-centre, and transmission and two kinds of forms of reflection are arranged, they when differentiating deviation with visual or CCD look-out.Visual method visual field is big, finds measured target easily, and CCD monitors that the visual field is little, but is not easy to produce visual fatigue when observing.Instrument in the market mainly is wherein a kind of mode, and every kind of all inevitable defective that must exist separately of mode can't reach the purpose that needs conversion at any time when using.
Summary of the invention
The utility model will solve the shortcoming of above-mentioned prior art, provides a kind of and can change visual field, detector visual field, reflective center mapped structure easy to use.
The utility model solves the technical scheme that its technical matters adopts: detector visual field, this reflective center mapped structure, mainly comprise object lens, eyepiece and CCD monitor, be provided with reflective mirror in the detector of center, reflective mirror is fixed on the mirror base, object lens link to each other with prism table by connecting lens barrel, the position of reflective mirror is corresponding with the prism on the prism table, and eyepiece is fixed on the detector of center by adapter sleeve, and the CCD monitor links to each other with mirror base by the connected set trim ring.
Described prism, reflective mirror, eyepiece are on the same light path line.
Described CCD monitor and reflective mirror are on the same light path line.
Be provided with the cross-graduation plate in the middle of described CCD monitor and the reflective mirror.
Described object lens are connected to form successively by telephotolens and microcobjective.
The effect that the utility model is useful is: the utility model will insert a reflective mirror in the Amici prism light path of switching in system, one cross-graduation target is imaged onto on the face of CCD in the reflective mirror incision, is imaged onto on the eyepiece graticule when reflective mirror shifts out.Can solve the effect that switch different visual fields like this.Make that having visual and CCD on same instrument simultaneously monitors both characteristics, change structure and when seeking target, utilize visual system to have the big characteristics in visual field, switch on the monitor when in fixed, operating, can alleviate visual fatigue.

Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
As shown in the figure, detector visual field, this reflective center mapped structure mainly comprises object lens 1, eyepiece 2 and CCD monitor 3, and object lens 1 are connected to form successively by telephotolens 12 and microcobjective 13, have enlarged the view finding scope, has improved the sensitivity that detects.Be provided with reflective mirror 4 in the detector of center, reflective mirror 4 is glued on the mirror base 5, and mirror base 5 is fixed on the outer cage by microscope base press strip 14, and mirror base 5 is provided with pull bar 15.Object lens 1 link to each other with prism table 7 by connecting lens barrel 6, and the position of reflective mirror 4 is corresponding with the prism 8 on the prism table 7, and eyepiece 2 is fixed on the detector of center by adapter sleeve 9, and CCD monitor 3 links to each other with mirror base 5 by connected set trim ring 10.Prism 8, reflective mirror 4, eyepiece 2 are on the same light path line; CCD monitor 3 is on the same light path line with reflective mirror 4, CCD monitor 3 and the reflective mirror 4 middle cross-graduation plates 11 that are provided with.
When reflective mirror 4 does not insert instrument, be imaged on the eyepiece 2 and read; When reflective mirror 4 inserts instrument, be imaged on the CCD monitor 3 and read, the differentiation line of cross-graduation plate 11 is become the centre of sphere at tested lens, utilize the autocollimation principle that cross-graduation plate 11 is returned as former road, rotate tested lens during measurement, eccentric if tested lens exist, then and then rotation of the cross on the cross-graduation plate 11, the size of radius of turn has been represented eccentric size, and this off-centre size can be read on the screen of CCD monitor 3.
In addition to the implementation, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
