Abstract
The utility model discloses an improved optical comparison goniometer device for measuring the range exceeding the measuring range of a light beam deflection angle. The utility model provides a technical scheme as follows: the improved optical comparison goniometer device comprises an optical comparison goniometer and a work platform thereof, as well as a reflecting device, wherein the reflecting device is arranged on the work platform of the optical comparison goniometer. The distance between two completely-separated reflecting images of a measured optical element is measured by taking the surface reflecting image of the reflecting device as a graduated scale. According to the improved optical comparison goniometer device disclosed by the utility model, the measuring range of a maximum angle of 1 degree of a general optical comparison goniometer is widened and the improved optical comparison goniometer device for measuring the range exceeding the measuring range of the light beam deflection angle is provided.
Description
Technical field:
The utility model relates to a kind of optical gauge, especially a kind of improvement optics comparison goniometer device that is used for measuring beam deflection angle no to scale scope.
Background technology:
The optics comparison goniometer is to utilize the optical autocollimating principle, and with the take measurement of an angle optical gauge of error of relatively method, it is simple in structure, uses extensively.It is poor to be mainly used in the optical parallel of measuring glass plate and various prisms, measures the verticality on two planes, or utilizes the deviation of standard angle gauge block measuring prism angle and standard angle, can also be used to measuring the angular error between the various installation base surfaces simultaneously.For example: measure the parallel error of parallel plane glass, the key groove of wedge of glass, the optical parallel difference of right-angle prism and various prisms and lateral vertical degree or the like.Therefore, obtained using widely at aspects such as the assembling of optics cold working, optical laboratory, optical instrument, detection, meterings.
But because the optics comparison goniometer is to measure according to the principle of optical autocollimating, light is outgoing from lens barrel, through after the detected element, must turn back in the lens barrel and just can measure.And the range ability of traditional optical comparison goniometer is 1 °, and for the optical element of beam deflection angle greater than 1 °, its two reflection images are separated fully, can't measure the distance between two reflection images.Therefore, for the optical element of beam deflection angle greater than 1 °, the traditional optical comparison goniometer just can't be measured.
Summary of the invention:
The utility model is in order to overcome the deficiency of existing optics comparison goniometer; On the basis of traditional optical comparison goniometer, increased a reflection unit; With the distance between two reflection images measuring separation fully, thereby a kind of improvement optics comparison goniometer device that is used for measuring beam deflection angle no to scale scope is provided.
The technical scheme that the utility model technical solution problem adopts is: a kind of improvement optics comparison goniometer device that is used for measuring beam deflection angle no to scale scope; It comprises optics comparison goniometer and its workbench; And reflection unit, described reflection unit is arranged on the workbench of optics comparison goniometer.Its characteristics are:
(1) described reflection unit can be a rectangular parallelepiped glass blocks.
(2) described reflection unit also can be a catoptron.
(3) lower surface of described rectangular parallelepiped glass blocks and one of them side process polishing.Its side of polishing is positioned at phase the other side of said optics comparison goniometer lens barrel.
(4) described catoptron vertically is positioned on the workbench of optics comparison goniometer, and its reflecting surface is positioned at phase the other side of said optics comparison goniometer lens barrel.
The utility model compared with prior art has following beneficial effect: 1, can the measuring beam deflection angle greater than 1 ° less than 2 ° optical element, enlarged the traditional optical comparison goniometer and be 1 ° measurement range to the maximum.2, simple in structure, be easy to realize.
Description of drawings:
Fig. 1 is the utility model specific embodiment vertical view;
Fig. 2 is the utility model specific embodiment right view;
Fig. 3 measures visual field figure for the utility model specific embodiment.
Embodiment:
As depicted in figs. 1 and 2, the 1st, the traditional optical comparison goniometer, the 5th, its workbench, the 2nd, the lens barrel of optics comparison goniometer, the 3rd, the measured optical unit, the 4th, reflection unit is rectangular parallelepiped glass blocks or catoptron.The lens barrel 2 of traditional optical comparison goniometer 1 is transferred to level; Be placed on the rectangular parallelepiped glass blocks of the measured optical unit 3, reflection unit 4 or catoptron on the workbench 5 of traditional optical comparison goniometer 1, the reflecting surface of the polishing side of the rectangular parallelepiped glass blocks of reflection unit 4 or the catoptron of reflection unit 4 is positioned at phase the other side of the lens barrel 2 of traditional optical comparison goniometer 1.As shown in Figure 3; 6 is the visual field of seeing; Rectangular parallelepiped glass blocks or the position of catoptron of adjustment reflection unit 4, use reflection unit 4 rectangular parallelepiped glass blocks or catoptron surface reflection as 9 measure distance between two reflection images 7 and 8 of the measured optical unit 3 be 30 '.The deviation that draws emergent light and the incident light of the measured optical unit 3 thus be 1 ° 30 '.
