Laboratory installation "Study of the spectrum of hydrogen" Naurash
The laboratory installation "Study of the spectrum of hydrogen" by Naurash consists of a spectrometer, a power supply and a set of line spectrum sources - gas-discharge tubes. The spectrometer is made on the basis of a diffraction grating and a CCD matrix located at the focus of the mirror behind the diffraction grating. To control the operation of the spectrometer and read information from it about the spectral composition of the analyzed study, a special computer program is used. Data is presented on a computer screen in the form of a spectrum - the dependence of radiation intensity on wavelength. The program has the necessary tools for analyzing spectra, including the ability to subtract the shadow spectrum. The sensitivity of the spectrometer is adjusted in the computer program that works with it by changing the time of exposure of the CCD matrix to radiation. The gas-discharge tubes included in the kit (except for hydrogen) allow you to check the calibration of the spectrometer (using the spectrum of mercury) and set a spectroscopic task to determine an unknown gas from its spectrum.
