Diffraction Grating Characteristics & Application Experiment

 
  Knowledge Introduction
 
    Diffraction grating is optical components by using multi-slit diffraction principle of optical dispersion, it is insisted by a large number of parallel to each other, equal width, equal spacing slit or groove composition. Because of high chromatic dispersion and high resolving power, it has been widely used in many fields, such as agriculture, astronomy, biology, chemistry, environment detection and component detection.
    In this experiment, we mainly study the characteristics of reflective grating, with clear structure, rich content, good operability, students can understand the principle of diffraction grating and monochromator deeply and improve the ability of experiment.
 

    Main points:
   
Diffraction phenomenon of grating and measurement of diffraction
       angle

   
Second order diffraction phenomenon of diffraction grating

    The principle and structure of grating spectrometer
