spectrometer
I. Experiment content:
1, the use of light reflection principle measurement prism Angle experiment;
2, using the principle of light refraction to measure the minimum deviation Angle of the prism, calculate the refractive index and dispersion of the prism glass experiment;
3, for light diffraction experiment;
4. Wavelength measurement experiment.
Two, the main technical parameters:
※1, parallel light tube, telescope system are made of LY12 material, imported sand black surface treatment process, good vision, beautiful;
- Focal length of objective lens: 143.33mm. Field of view Angle :8° through light aperture: Φ33㎜;
- Magnification: 5.25;
- Slit width adjustment range: 0-5 mm;
5, lighting using long life high brightness green light-emitting diode.
6. Features:
※①, large aperture, high magnification, the observed image is clear;
