Abstract
This paper will analysis and show up of the adjusting and exploration of the optical instrument in college physics experiment from the structure, principle and phenomenon, and then to show how to improve the practical ability of the students. The main of the optical instrument in the college physics experiment are optical lever amplification devices,microscope(micro eyepiece),telescope,spectrometers and so on Spectrometer which as one of the most important optical devices in the college physics experiment will be key to expounding,putting forward a new adjustment method of the spectronmeter,because it not only can be used to measure the interference of light, refraction, scattering and other experimental phenomena, can also be used to measure the refraction angle, light wavelength, polarization angle and other physical quantities, and it includes the microscope eyepiece, telescope and collimator components of various optical instruments from its structure, so regulate the spectrometer experiment on college students to improve practical ability is very helpful
