Problems solved by technology

This structure has the following disadvantages: 1. The cooperation between the lens mounting plate and the connecting seat is not easy to control. If it is too tight, it will be difficult to pull out when wiping. If it is too loose, it will affect the vacuum; Change; 3. Since the lens also isolates the vacuum chamber from the argon atmosphere (2 atmospheres), the vacuum will be destroyed when plugging and unplugging

Embodiment Construction

[0010] The present invention will be further described below in conjunction with the accompanying drawings.

[0011] Such as Figure 2-Figure 3 Shown is a lens installation structure of a direct-reading spectrometer, the lens 4 is fixedly installed on the second connection seat 2 in the argon atmosphere; the side wall of the second connection seat 2 is provided with a cleaning opening 5 for directly extending into the wiping lens, The second connecting seat is provided with a dust shield 6 for sealing the cleaning opening 5; the second connecting seat 2 is directly docked and fixedly installed with the first connecting seat 1 of the vacuum chamber.

[0012] In the existing structure, the defect is that the lens 4 is movable, and the lens must be pulled out for wiping.

[0013] In the present invention, the lens 4 and the spectroscopic chamber are installed together. The wiping is carried out from the side wall of the second coupling seat 2; the cleaning opening 5 is large en...

Abstract

The invention discloses a lens mounting structure of a direct-reading spectrometer. The lens mounting structure comprises a lens. The lens mounting structure is characterized in that a lens is fixedly arranged on a second coupling seat in an argon atmosphere; a clean opening for directly extending to wipe the lens is arranged on the lateral wall of the second coupling seat; a dust baffle plate for sealing the clean opening is arranged on the second coupling seat, and the second coupling seat and the first coupling seat of a vacuum cavity are directly butted and fixedly arranged together. The lens mounting structure of the direct-reading spectrometer, provided by the invention, is simple in structure and convenient to use; a special structure is adopted; the lens does not need to be dismantled when the lens is wiped and cleaned; vacuum does not need to be discharged; and a constant-temperature system does not need to be damaged, and the position of the cleaned lens does not change basically, so that the effect on an optical system in a lens maintaining process achieves the minimal extent, and the cleaning is rapid and convenient.

Description

technical field [0001] The invention relates to a lens installation structure of a direct reading spectrometer. Background technique [0002] The lens of the direct-reading spectrometer is to separate the vacuum environment of the spectroscopic chamber from the outside world, and at the same time focus the excited light on the main optical axis. The existing direct-reading spectrometer lens is separated from the coupling seat of the spectroscopic chamber and the excitation table, such as figure 1 As shown, the first connecting seat 1 and the second connecting seat 2 clamp the lens mounting plate 3, when wiping, pull out the lens mounting plate 3, and insert the lens 4 after wiping. This structure has the following disadvantages: 1. The cooperation between the lens mounting plate and the connecting seat is not easy to control. If it is too tight, it will be difficult to pull out when wiping. If it is too loose, it will affect the vacuum; Change; 3. Since the lens also isola...
