Embodiment Construction

[0016] The miniaturized ultraviolet spectroradiometer for high-altitude balloon test manufactured by the method of the present invention consists of an optical system 1, a detector 2, an electric control system 3 and a housing 4.

[0017] 1. Optical system 1 such as figure 1 As shown, it includes: the incident slit 1-1, the middle slit 1-2 and the exit slit 1-3 are fixed on the body of the housing 4, and the first concave spherical grating 1-4 is fixed on the housing 4 , Mirror group 1-5, second concave spherical grating 1-6.

[0018] The width of the entrance slit 1-1 and the exit slit 1-3 can be 0.25 mm, and the length of the entrance slit 1-1 and the exit slit 1-3 is 6 mm. The slit width of middle slit 1-2 can adopt 0.25mm, and the length of middle slit 1-2 is 6mm. The size of the first concave spherical grating 1-4 and the second concave spherical grating 1-6 can be selected according to actual needs. Mirror group 1-5 is made up of two plane mirrors, and the size can be...

Abstract

The invention belongs to the spectrum instrument technology field and is the facture of mini ultraviolet spectrum radiator of upper air balloon experiment: connect the photic components of the photic system to the framework and fix them with the shell; the wavelength revolving lead-screw, the nut and the sway bar can scan in 180nm-400nm range; the linear expansion coefficients of the raster framework, the nut, the sway bar, the lead-screw and the shell are matched; the silica gel seals the space between the detector and the detector shell and in the high-pressure source. The invention solves the problem of the traditional device, can bear the low temperature condition and ensure the wavelength precision.

Description

Technical field: [0001] The invention belongs to the technical field of spectroscopic instruments, and relates to a miniaturized ultraviolet spectroradiometer system applied to high-altitude balloon tests. Background technique: [0002] In the past 20 to 30 years, the research on solar / atmospheric ultraviolet spectrum observation has been very active in the world. In order to meet the international development and the needs of related domestic research, in the late 1980s, with the support of the 863-2 project, Changchun Institute of Optics and Mechanics developed a solar / atmospheric ultraviolet spectroradiometer and carried out long-term ground observation of solar / atmospheric ultraviolet spectroscopy. Get a lot of valuable data. In the early 1990s, the solar / atmospheric ultraviolet spectrum high-altitude balloon observation experiment was carried out. Traditional ground-based solar / atmospheric ultraviolet spectroradiometers are no longer suitable for high-altitude balloon...
