Embodiment 1

[0058] In this embodiment, a Paul combined prism processing technology, such as figure 2 As shown in the figure, the Paul combined prism is composed of isosceles right-angle prisms glued together. The isosceles right-angle prisms include isosceles right-angle prism I1, isosceles right-angle prism II2, isosceles right-angle prism III3 and isosceles right-angle prism IV4, processed Steps like figure 1 The specific steps are as follows:

[0059] S01, processing isosceles right-angle prism:

[0060] Ⅰ. Grinding and polishing areosceles right-angle prism Ⅰ1, isosceles right-angle prism Ⅱ2 and isosceles right-angle prism Ⅲ3, and isosceles right-angle prism Ⅳ4 with large side length of 10×20mm; The process parameters for controlling each of the isosceles right-angle prisms are: the precision of the 45° angle, the 90° angle and the tower difference are controlled within 8", and the perpendicularity of the large face and the two right-angled faces to the triangle side face is controlled wi...

Embodiment 2

[0068] In this embodiment, a Paul combined prism processing technology, the structure of the Paul combined prism is the same as that in embodiment 1, and the processing steps are as follows:

[0069] S01, processing isosceles right-angle prism:

[0070] Ⅰ. Grinding and polishing areosceles right-angle prism Ⅰ1, isosceles right-angle prism Ⅱ2 and isosceles right-angle prism Ⅲ3, and isosceles right-angle prism Ⅳ4 with large side length of 20×40mm; The process control of each of the isosceles right-angle prisms is: the precision of the 45° angle, the 90° angle and the tower difference are all controlled within 10", the perpendicularity of the large face and the two right-angle faces to the triangle side face is controlled within 30", and the size The tolerance is ±0.02mm; the surface flatness of the large surface is ≤1 / 10λ, and the surface finish is 15-20; the surface flatness of the two right-angled surfaces is ≤1 / 8λ, and the surface finish is 30-40;

[0071] Ii. Coating each of the i...

Embodiment 3

[0078] The Paul combined prism processing technology in this embodiment, the processing steps are basically the same as those in the first and second embodiments, and the difference and improvement are as follows: image 3 As shown in, the processing method of the isosceles right-angle prism is as follows:

[0079] Ⅰ. Glue the blank to the large surface of the triangular prism supporting body 5 with optical glue, keeping the large surface of the blank facing upward, and then apply the right-angled surface glue at the bottom of the triangular prism supporting body 5 to a circular tray with a diameter of 300mm 6, and then grind and polish the large surface of the blank;

[0080] Ⅱ. Wipe clean the processed large surface with a mixture of ethanol and ether = 1:3, and then apply the large surface of the blank to the large surface of the triangular prism body 5, and ensure that the right-angle side of the blank faces upwards. Then, the right-angled surface of the triangular prism leanin...

Abstract

The invention discloses a processing technology of a Porro combined prism, and relates to the technical field of Porro prism processing. The method comprises the following steps: S01, processing an isosceles right-angle prism: i, grinding and polishing to process an isosceles right-angle prism I, an isosceles right-angle prism II, an isosceles right-angle prism III and an isosceles right-angle prism IV; ii, respectively carrying out coating treatment on each isosceles right-angle prism; S02, gluing the large surfaces of the isosceles right-angle prism I and the isosceles right-angle prism II to form a cube beam splitter prism; S03, processing a Porro combination prism: i, gluing an isosceles right-angle prism III and a beam splitter prism on the large surface of an isosceles right-angle prism IV in sequence, calibrating and debugging by using an angle measuring instrument with the precision of 15 ''while gluing, and irradiating and curing for 10-15 seconds by using an ultraviolet lampuntil two light rays in the angle measuring instrument are observed to be superposed by naked eyes; and ii, after all gluing is finished, irradiating and curing for 15-18 minutes by using an ultraviolet lamp. The method is simple in machining procedure, high in efficiency and high in finished product percent of pass and product consistency.

Description

Technical field [0001] The invention relates to the technical field of Paul prism processing, in particular to a Paul combined prism processing technology. Background technique [0002] Paul's combination prism is an optical prism product that uses a combination of multiple prisms. The telescope using Paul's combination prism can maintain high resolution and high light flux from the objective lens to the eyepiece, and can achieve brighter and clearer imaging effects. Compared with other ordinary Paul prisms, the optical performance is better. [0003] For the production of Paul’s combined prisms, because it is composed of multiple triangular prisms, the angles of the exit and the incident light of the finished product usually deviate, and the smaller the deviation of the angle between the exit light and the incident light, the better the optical performance. The processing technology is also more complicated. The existing Paul combined prism processing technology is backward, the...
