Abstract
The invention discloses an orthogonal telescope, relates to telescopes, in particular to a reflective telescope. The orthogonal telescope comprises a planarea reflective curve surface. An intersected curve of the planarea reflective curve surface and a straight line generator vertical plane is a secondary curve. The planarea reflective curve surface is formed by grinding glass material in one way or bending and fixing mirror type planar structure which is bendable. Every three planarea reflective curve surfaces form an objective lens group, wherein two of the three planarea reflective curve surfaces locate at different positions on the same optical path, and straight line generators thereof are perpendicular mutually in the optical path. One of the two planarea reflective curve surfaces is wider and with hollow center, thereby bringing convenience for light to emit from the middle to the third planarea reflective curve surface and then emit to an eyepiece. Compared with the prior art, the orthogonal telescope has the advantages that large caliber manufacturing of the orthogonal telescope is easy to realize, and effects of paraboloid objective can be achieved.
Description
Technical field
The invention relates to a kind of telescope, more particularly, is about a kind of autocollimator.
Background technology
At present, the common autocollimator of selling on the market, its object lens are difficult to make heavy caliber, and heavy caliber object lens manufacturing cost is expensive.Grinding of parabolic object lens of while is more difficult.Therefore, the present invention proposes a kind of autocollimator, and it is easy to the heavy caliber manufacturing, and can reach the effect of parabolic object lens.
Summary of the invention
The purpose of this invention is to provide a kind of autocollimator that is easy to the heavy caliber manufacturing and can reaches the effect of parabolic object lens.Quadrature telescope of the present invention comprises planarea type reflecting curved surface.The curve that described planarea type reflecting curved surface and straight edge line vertical plane intersect all is quafric curve.Because be quafric curve, thus can focused ray, when for para-curve, can reach by the stack of two reflecting curved surfaces the effect of parabolic object lens.Because be planarea, so make parabola shaped and make easily the heavy caliber telescope easilier, described planarea type reflecting curved surface can form or the planar material bending of flexible mirror type fixedly forms by unidirectional the grinding of glass-like materials.3 of described planarea type reflecting curved surfaces form one group of telescope objective.In described 3 planarea type reflecting curved surfaces the reflective surface of first planarea type reflecting curved surface and second planarea type reflecting curved surface mutually over against and its straight edge line mutually vertical, the mode that focuses on respectively by light pairwise orthogonal direction branch forms real image, therefore to have at least a pair of planarea type reflecting curved surface to be on the priority diverse location of same light path and straight edge line mutually vertical in light path.Described first planarea type reflecting curved surface is longer and middle hollow out more described second the planarea type reflecting curved surface of length on its straight edge line vertical line direction is equidirectional, passes through from the center to make things convenient for light.The 3rd planarea type reflecting curved surface is positioned at described first planarea type reflecting curved surface center back in described 3 planarea type reflecting curved surfaces.Described the 3rd planarea type reflecting curved surface straight edge line is parallel with described second planarea type reflecting curved surface straight edge line.Described the 3rd planarea type reflecting curved surface focus above it.Described the 3rd planarea type reflecting curved surface top is mounted with eyepiece.The focal plane of described first planarea type reflecting curved surface is farther from eyepiece in light path, uniting described the 3rd planarea type reflecting curved surface, can to correct the aspect ratio that causes because of the first two planarea type reflecting curved surface focal length difference unbalance, because the effect of described the 3rd planarea type reflecting curved surface is correction image, technology is also unnecessary, therefore will have at least the straight edge line of a pair of planarea type reflecting curved surface mutually vertical in light path.Companion's axle directional light is through the approximate straight line that converges to its focal plane of first planarea type reflecting curved surface reflection, through second approximate line segment that converges to another focal plane of planarea type reflecting curved surface reflection, correct into point on the same plane by the 3rd planarea type reflecting curved surface, be reduced to directional light by eyepiece.
The invention has the beneficial effects as follows: it is easy to the heavy caliber manufacturing, and can reach the effect of parabolic object lens.Only need Large Surface Mirror profile shape material bending fixed or glass-like materials is carried out one direction grinding, just can reach the purpose of heavy caliber manufacturing, and make easily parabola shapedly, can reach the effect of parabolic object lens.For the heavy caliber telescope of identical effective aperture, it is with low cost.
