Michelson interferometer

 FBEM-5702

 

 

DETAILS

Experiments:

a) Observing the interference of light(equal thickness fringes,isoclinic fringes,white light color fringes);

b) Measuring the wavelength of He-Ne laser;

c) Measuring the coherent length of light source and filter;

d) Observing the interference phenomenon of multi beams with Fabri Perot system;

e) Measuring the thickness and refractive index of filter;

f) Measuring the air refractive index (Need FBEM-5702-02).

Key features:

a) Two-dimension precise adjustable screw pitch:0.25mm;

b) Pedestals and guide rails which are made of cast iron lead to good stabilities;

c ) Reading accuracy:0.0001mm;

d) The planeness of beam splitters and compensation plates:λ/30.

 Specifications:

The strobe of movable mirror is 100mm or 200mm

Micro-handwheel’s indexing is 0.0001mm

Wavelength measurement accuracy: when the fringe number is 100, the relative error of monochromatic wavelength less than 2%

Linearity error of track is ±16 "

Flatness of splitting plate and compensation plate is λ/30

Flatness of movable mirror and reference mirror is λ/20

Pitch of precision 2D Mount is 0.25mm

 

Typical Experiments And Data

a) Observing the interference of light (equal thickness fringes,isoclinic fringes,white light color fringes

b) Measuring the wavelength of He-Ne laser

N: number of turns; di: distance; λi: wavelength

λaverage = 0.000669888mm = 669.888nm

U = 0.00005mm = 50nm (Instrument error)

λ = λaverage ± U = 669.888 ± 50nm 4

 

c) Measuring the coherent length of light source and filter;

 

d) Observing the interference phenomenon of multi beams with Fabri Perot system;

 

e) Measuring the thickness and refractive index of filter;

 

f) Measuring the air refractive index (Need FBEM-5702-02).
