HIGHER EDUCATION SPECTROGONIOMETER

Educational content :

• Characterization of a grating, a prism
• Study of line spectra
• Separation of a sodium doublet
• Minimum deviation of a prism
• Autocollimation

This spectrogoniometer permits the study and characterization of chromatic dispersion systems i.e. mainly prisms and gratings.

This device is designed for higher education needs. It has been built to give a minute of arc precision, and it is very resistant.

The device has 2 arms composed of:

·         A symmetrical collimated slit adjustable with a micrometric vernier.

·         An autocollimator telescope with eclipsable lighting.

It also has: spectroscopy auxiliary collimator enabling the display of a graduation in the background of the spectrum.

SPECTROGONIOMETRY EXPERIMENTAL KIT

Educational content :

• angular deviation
• Autocollimation
• Spectrometry
• gratings
• prisms

This set permits an advanced study of all goniometry and spectrometry parameters. Ten practical can be carried out with a high precision level: goniometer or spectroscope functioning, dispersion phenomena by prisms or gratings, luminous spectrum analysis, the separation of the sodium doublet, and the resolution power.

BASIC GONIOMETRY EXPERIMENTS

Educational content :

• angular deviation
• autocollimation
• line spectra
• dispersion
• gratings
• prisms

This set introduces the study of prism and grating dispersions. The device functioning principles and the autocollimation techniques can be studied. The dispersion study of different prisms and gratings can be done with the mercury spectral source.
