Problems solved by technology

This type of product has a complex structure and is very bulky
[0004] Second, integrated design, the two-dimensional translation platform is designed as a whole, and the structural optimization of the entire translation platform is considered in the design. The basic design idea is that the screw rotates to drive the movement platform to move on the guide rail, and the spring provides elastic force to eliminate the gap. The volume is slightly smaller than the first solution, but the volume is still relatively large, and most of them can only be used for the adjustment of reflective optical devices
The disadvantage of this solution is also that it is bulky, and the volume of three-dimensional translation is larger
[0007] Through the analysis of the prior art, it is concluded that the translation stage in the prior art has a large volume and a large mass, and because the optical devices are generally installed outside the translation stage, the volume of the translation stage is further increased, so the translation stage in the prior art The translation stage is not conducive to product integration, and it is difficult to be used in occasions with strict volume requirements

Abstract

The invention relates to the technical field of adjustment of optical devices, in particular to a translation stage capable of containing devices, which comprises a base plate and a cover plate, wherein the centers of the base plate and the cover plate are respectively provided with a round light hole, and the base plate is connected with the cover plate by a screw to form a semi-closed cavity capable of containing optical devices. By containing the optical devices in the translation stage, the invention achieves the advantages of concise mechanical drive chain, small volume, compact structure and convenient operation, thereby being very suitable for product integration or situations having stringent requirements for volume. The invention can be used for two-dimensional or three-dimensional translational adjustment of optical devices such as small pinholes, slits, lenses, reflectors and the like.

Description

technical field [0001] The invention relates to the technical field of optical device adjustment, in particular to a device built-in translation platform. Background technique [0002] Translation stages, especially two-dimensional and three-dimensional translation stages are commonly used components in optical adjustment devices. Currently, commonly used technologies include: [0003] First, a modular design is adopted to superimpose two one-dimensional translation stages to form a two-dimensional translation stage. The basic design idea of ​​each one-dimensional translation table is that the screw rotates to drive the motion table to move on the guide rail, and the spring provides elastic force to eliminate the gap. The base of another translation platform is fixedly connected on the motion platform of the first translation platform. This design solution is often bulky and can only be used for the adjustment of reflective optical devices, not for the adjustment of transm...
