Embodiment Construction

[0013] The specific implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings and examples, but the protection scope of the present invention should not be limited thereby.

[0014] see figure 1 The three-dimensional view of spectrometer sample support of the present invention and figure 2 Schematic diagram of the transmission mechanism of the spectrometer sample holder of the present invention. The spectrometer sample support of the present invention uses the principle of gear transmission to control the rotation angle of the sample support by rotating the driving gear. Draw a scale on the driving gear, install a gear under the stage, and then use the principle of gear transmission to control the rotation angle of the sample holder by turning the driving gear. The sample can be firmly fixed in the sample holder and rotated with the axis to a precise angle.

Abstract

The invention discloses a spectrograph sample bracket, which comprises a transmission mechanism, an objective table, a rotation shaft and an elastic clamp. The transmission mechanism comprises a driving wheel, a first gear below the driving wheel and a second gear below the objective table; and the entire transmission mechanism is encapsulated in a rectangular shell. A first baffle is arranged on the driving wheel; a second baffle connected with the inner surface of the shell of a box is also arranged above the driving wheel; and under the joint action of the two baffles, the driving wheel can only rotate within 180 degrees clockwise or anticlockwise. Through the invention, a spectrograph sample bracket with a continuously adjustable angle is designed, and a sample on the sample bracket can be rotated at a required angle so that the uniformity of the sample at each angle can be detected.

Description

technical field [0001] The invention relates to a support, in particular to a spectrometer sample support. Background technique [0002] The current spectrometer sample holder has an axial slide, and this kind of holder passes through four positioning holes on the sheet, and it is cleverly designed as a slidable part. The advantage of this design is that in addition to measuring the transmittance parameters of the filter, the filter on the bracket can be placed in different lateral positions through four positioning holes, so that the uniformity of the entire filter can be evaluated. Moreover, the bracket has a simple structure and a smooth inner wall, which hardly causes any abrasion to the optical filter. The disadvantage of this design is that the uniformity of the optical filter can only be detected vertically due to the axial sliding. There are certain limitations. Contents of the invention [0003] In order to overcome the shortcomings of the above-mentioned prior...
