Problems solved by technology
[0005] However, this adjustment structure will cause the center of the grating to shift and the center of the optical path to shift, thereby reducing the resolution of the imaging and resulting in a low overall precision of the spectrometer; secondly, the assembly of this structure is relatively complicated and takes up The space is large, so that the space required for it to be placed, the volume of the vacuum chamber, becomes larger. Due to the above reasons, the industry needs to find a method that can avoid the problem of low overall accuracy of the spectrometer caused by the offset of the grating center and The structure is simpler, the adjustment mechanism with a smaller vacuum chamber is required

The invention discloses a grating two-dimensional inclined frame for a spectrometer. The grating two-dimensional inclined frame comprises a base and three supports, wherein the base comprises support through-holes, the support is fixedly connected with the base through the support through-holes, and each two connecting lines of centers of the support through-holes form an equilateral triangle; the central position of the base is provided with a cavity for installing gratings, and the cavity moves along with the base; the support comprises a base adjusting mechanism, a support column, an adjusting component and a fixing component; one end of the base adjusting mechanism is connected to the support column and fixedly connected with the adjusting component, and can move along with the adjusting component, thereby adjusting variations of the position of the base connected with the base adjusting mechanism; the adjusting component is installed on the support column and can move on the support column; and the position of the fixing component is fixed through a through-hole adjusting component on the adjusting component. The grating two-dimensional inclined frame provided by the invention for the spectrometer can enable the structure to be more compact and the assembly to be more convenient, and enable the size of the required vacuum chamber to be smaller.
Description
technical field [0001] The invention belongs to the field of optics, and relates to a grating two-dimensional inclined frame used on a spectrometer. [0002] Background technique [0003] The invention belongs to the technical field of spectroscopy, and improves the accuracy of grating adjustment, thereby improving the overall performance of the spectrometer. [0004] The existing concave grating tilting frame mostly adopts a similar hinge method for position adjustment, such as figure 1 As shown in the figure, that is, one end is a rotating shaft, changing the height of the other end, and adjusting the right split card 11 can realize the rotation of the upper page 12 and the next page 14 through the rotating shaft 13, then the end of the hinge with the split card 11 can be opened and closed, When the next page 14 is installed on a certain plane, the tilting motion of the previous page 12 can be realized. When the grating is installed on the upper page 12, the angle of the...
