Lens-adjustable all-sealed optical system

Abstract

The invention relates to the technical field of optical systems, in particular to a lens-adjustable all-sealed optical system. The lens-adjustable all-sealed optical system comprises a two-dimensional galvanometer, an industrial video camera, a hollow 45-degree totally mirror seat, a 45-degree totally reflecting mirror base, a 45-degree totally reflecting mirror component, a fixed sleeve and a sliding sleeve, wherein a light-transmitting circular hole is formed in the top part of the two-dimensional galvanometer, the 45-degree totally reflecting mirror component is arranged in the 45-degree totally reflecting mirror base, the 45-degree totally reflecting mirror component is connected with an adjusting screw extending to the outer part of the 45-degree totally reflecting mirror base, and the 45-degree totally reflecting mirror component can swing in the 45-degree totally reflecting mirror base in a two-dimensional manner by adjusting the adjusting screw. According to the lens-adjustable all-sealed optical system, the precise optical system is fully sealed in a cavity, the lens-adjustable all-sealed optical system ensures that the optical device to be adjusted can perform swing adjustment in the X, Y directions and axial distance adjustment effectively and reliably without opening the sealed cavity, and the whole adjusting process does not change partial environment of the sealed cavity, thus the optical system can keep good cleanliness throughout the process.

Description

technical field [0001] The invention relates to the technical field of optical systems, in particular to a fully sealed optical system with adjustable lenses. Background technique [0002] What the optical system is most afraid of is dust. A particle of dust will not only change the optical characteristics of the system, but even cause damage to the entire optical system. Therefore, the optical system under test is always placed in a clean room. However, the data obtained from the clean room can only be used as a guiding parameter. In the industrial design, the parameters of the optical device need to be adjusted according to the specific machine. [0003] There are two common approaches: [0004] First, the entire optical system is made into a clean cavity as a whole, installed and debugged in the clean room of the factory, and then handed over to the user after sealing. This will require the user not to open the sealed cavity in a normal environment, which will be difficu...

Problems solved by technology

[0009] 1. There must be a gap between the telescopic sleeve and the telescopic sleeve, otherwise it cannot slide easily, which will lead to failure to build a completely sealed internal cavity, and the internal and external environments are actually connected. Therefore, the unsealed sleeve It is difficult to protect the optical path, let alone "sealing"

[0010] 2. This kind of telescopic sleeve is only suitable for vertical installation, and it is not suitable for horizontal installation, because horizontal installation will cause the middle sleeve to "slump down". Obviously, so that the laser will hit the inner wall of the telescopic tube, thus affecting the output of the optical path
