The technical problem required to be solved includes providing a cylindrical right-angled prism. The technical scheme for solving the technical problem includes that the cylindrical right-angled prism comprises a vertical surface, a bottom plane, an inclined surface and a cylindrical surface, the vertical surface is perpendicular to the bottom plane, included angles between the inclined surface and the vertical surface and between the inclined surface and the bottom plane are both 45 degrees, the width of the bottom plane is identical to the clear aperture D, the distance from the bottom plane to the center of the cylindrical surface is D/2, and the diameter phi of the cylindrical surface is D/2. The cylindrical right-angled prism is simple in processing technique, low in cost and convenient and fast in mounting and debugging, and increases work efficiency.
Description
Technical field
The utility model belongs to a kind of a kind of optical element that is used on the optical instrument light path that relates in the optical instrument technical field.
Background technology
Right-angle prism plays important effect in optical instrument, it makes the light path trend of optical system turn back 90 °; Thereby, in a lot of optical systems, having obtained application, it brings great convenience for simplifying optical system with improvement optical-mechanical structural design, processing.
The prior art the most approaching with the utility model is general right-angle prism, on a lot of textbooks, can find on the popular science books, as illustrated in fig. 1 and 2, comprises vertical plane 1, baseplane 2, inclined-plane 3.Vertical plane 1 is perpendicular to baseplane 2, and the angle between inclined-plane 3 and vertical plane 1 and the baseplane 2 is 45 °.
A branch of light and inclined-plane 3 angle at 45 incidents, 3 beam reflected from the inclined-plane become 90 ° of angles to penetrate with incident light.
The subject matter that the right-angle prism of this kind shape brings is: bring great difficulty for the Design of Mechanical Structure and the processing technology at the optical-mechanical position that right-angle prism is installed, and the shape more complicated of microscope base, difficulty of processing is very big.Cost is also high.Being connected of square microscope base and circular lens barrel also is the comparison difficulty.
Summary of the invention
In order to overcome the defective that prior art exists, the purpose of this utility model is to simplify optical-mechanical structural design and processing technology that right-angle prism microscope base position is installed, reduces cost, offer convenience a kind of cylindrical straight angle prism of ad hoc meter for simultaneously the Installation and Debugging right-angle prism.
The technical problems to be solved in the utility model is: a kind of cylindrical straight angle prism is provided.The technical scheme of technical solution problem such as Fig. 3, Fig. 4, shown in Figure 5: comprise vertical plane 4, baseplane 5, inclined-plane 6, the face of cylinder 7; Vertical plane 4 is vertical with baseplane 5, and the angle between inclined-plane 6 and vertical plane 4 and the baseplane 5 is at 45, and the width of baseplane 5 is identical with clear aperture, represents with D in Fig. 4, and the distance at 7 centers to the face of cylinder, baseplane 5 is D/2, and the diameter phi on the face of cylinder 7 is
A branch of light and inclined-plane 6 angle at 45 incidents, the folded light beam direction on inclined-plane 6 will become 90 ° of angles to penetrate with incident beam.
Good effect of the present utility model: the processing technology of cylindrical straight angle prism is simple, and cost is low, and it is convenient to bring for the Installation and Debugging prism, increases work efficiency.
