Abstract

The embodiment of the invention discloses a stationary Fourier spectrum apparatus. The stationary Fourier spectrum apparatus includes a front optical structure, a double right angle beam splitter anda back optical structure, wherein the front optical structure includes a triangle flat mirror, a first spherical mirror above the triangle flat mirror, and a slit; the double right angle beam splitterincludes a first trapezoid prism and a second trapezoid prism; the lower bottom surface of the first trapezoid prism and the lower bottom surface of the second trapezoid prism staggered by the presetdistance to paste together to form a beam splitting surface; and the back optical structure includes a second spherical mirror and a cylindrical surface reflector. The stationary Fourier spectrum apparatus is based on the double right angle beam splitter, and utilizes the reflecting structure except for the beam splitter, thus effectively folding the optical path to reduce the volume of the wholesystem and effectively widen the spectral range.

Description

technical field [0001] The invention relates to the technical field of spectrum measuring instruments, in particular to a static Fourier spectrum device, in particular to a reflective static Fourier spectrum device based on double right-angle beam splitters. Background technique [0002] Spectroscopic instruments are powerful tools for analyzing the composition and structure of substances. They are widely used in scientific research fields and industries such as environmental monitoring, chemical analysis, biomedicine, national defense and optoelectronic functional materials, and online real-time monitoring in these fields and industries Requirements such as portability and portability have promoted the development of miniaturization of spectroscopic instruments, and have broad application prospects. [0003] Traditional Fourier spectroscopy devices are difficult to achieve a compact structure due to the use of a large number of components. The moving parts in the tradition...
