PRECISION INTERFEROMETER
DescriptionMichelson Interferometer
Exp-1 Interference fringes observation.
Exp-2 Equal thickness interference.
Exp-3 Determination of wavelength.
Exp-4 Refractive index of transparency slice.
Exp-5 Equal inclination interference.
Exp-6 White light interference.
Exp-7 Precise comparing of wavelengths.
Exp-8 Refractive index of air.
Fabry-Perot Interferometer
Exp-9 Multiple beam Interference
Exp-10 Measurement of the wavelength separation of sodium D-lines.
Exp-11 Measurement of wavelength of He-Ne laser.
Twyman-Green Interferometer
Exp-12 Demonstration of Twyman-Green interferometer.
This equipment combines the historically important Michelson interferometer, the high resolution Fabry-Perot interferometer and the useful Twyman-Green interferometer.
Measurements are precise in three classical modes of operation. Switching between the three modes of operation and aligning components are very simple, as this complete set of high quality components is carefully mounted on a heavy, stable base.
