Abstract
The invention belongs to the field of spectrometers and discloses a novel spectrometer, comprising a spectrometer internal part, a condensing lens, an array detector, an optical grating, a collimating lens, an optical grating joint, an incident light, an entrance slit, an interferometer, a spectrometer optical system, a photoelectric sensor, a peripheral processor, a data acquisition card, industrial personal computer processing platform, a backstage processing program, a feedback control circuit, a feedback control lens, and a refracted light. The light passes through the optical grating joint, then enters the collimating lens, then is refracted to the optical grating, then is refracted to the collimating lens and then is refracted to the array detector. The spectrometer optical system comprises the interferometer and the photoelectric sensor. According to the invention, through changing the light source of the spectrometer, the spectrometer has following advantages such as low energy consumption, light in weight, strong shock resistance, and long service life. Astigmatism is measured by use of the focal power so that when astigmatism is corrected by use of a cylindrical lens, the position is not limited and the cylindrical can be placed according to structure requirement at will. Aberration correction of broadband is realized by use of a method for determining the image plane angle of an image spectrometer.
