Product Description


  • To determine the wave length of monochromaticlight (using sodium light source or He- Ne laser).


  • Precise measurement, mirror control isextremely fine with the micrometer of least count of 0.0001mm.
  • Heavy base for high stability
  • The mirrors and beam splitter are flat upto λ/8.

Principleand Working :

When a coherent light beam enters into beamsplitter, it is divided into two parts, thus two beams travel in differentdirections, are reflected into each other through two mirrors forminginterference patterns when they are combined and superimposed. In the presentsetup, measuring the wavelength of sodium light or He-Ne laser, using anequation: λ=2.D/n

Where, D is the total displacement whereas nis the number of intensity maxima counted
