Problems solved by technology

However, the gluing of optical prisms that are not transparent to visible light cannot be processed by the gluing method of optical prisms that are transparent to visible light, especially the correction and measurement during the gluing process of optical prisms that are not transparent to visible light cannot be realized.
Therefore, at present, only the absolute goniometer can be used for the production and processing of optical prisms that are not transparent to visible light. complex

Embodiment 1

[0036] The gluing process of the prism assembly 10 of the first embodiment is in a clean and dark environment, the ambient temperature is 20-25 degrees Celsius, and the relative humidity of the environment is less than 60%.

[0037] Such as image 3 Shown is Embodiment 2 of a method for gluing a non-visible light-transmitting prism component according to the present invention: producing a prism component 20 with an inner angle of 150°. The prism assembly 20 is completed by two prism components, the two prism components are respectively prism four 4 and prism five 5 , prism four 4 has plane four 41 , and prism five 5 has plane five 51 . The manufacturing steps of the 150° prism assembly 20 are as follows:

[0038] 1) Select a 30° right-angle prism standard angle block, and glue it with flat glass to obtain a 150° standard part 7, and the error of the 150° standard part 7 is controlled within 2 seconds.

[0039] 2) Wipe and clean the two prisms with analytical pure alcohol.

Abstract

The invention relates to a method for manufacturing an opaque visible light prism component by gluing. The gluing manufacturing method comprises the following steps: manufacturing a standard comparison component suitable for measuring a comparison prism assembly; selecting optical glue, combining cleaned prisms and gluing the combined prisms with the optical glue; fixing the prim assembly manufactured by gluing on a fixing fixture with plasticene for curing for 12-14 hours; comparing and measuring the manufactured prism assembly and the standard comparison component through a dual-tube angular instrument, and slightly adjusting the angle between the glued prisms in order that the prism assembly meets the requirement on the final angle; comparing and measuring the prism assembly manufactured and the standard comparison component finally through the dual-tube angular instrument. The method is high in accuracy, and is easy to operate. The requirement on measuring apparatuses and instruments used in a machining process is not too high, the dependence on expensive absolute angular instruments is prevented, the cost is low, the economical efficiency is high, machining and measurement can be performed simultaneously, and the quality of the manufactured opaque visible light prism component can be improved effectively.

Description

technical field [0001] The invention belongs to the technical field of optical technology, and in particular relates to an optical gluing manufacturing method for high-precision non-transparent visible light prism components. Background technique [0002] The optical system is the core of optoelectronic instruments, which determines the most basic performance and indicators of optoelectronic instruments. In order to make the optical system have a good image quality or for the convenience of manufacture and to achieve a certain use effect, two or more optical parts are often glued together with optical glue in the optical system to make optical glued parts. [0003] From the perspective of light transmission, optical parts are generally divided into two categories: one is through visible light, and the other is through invisible light. Common optical parts are optical prisms. In the gluing production of high-precision optical prisms, collimator and absolute goniometer are g...
