Product Description


A plano-convex lens is placed with its convex surface on the optically plane glass plate so as to enclose a thin film of air of varying thickness between the lens and the plate. Light from an extended monochromatic source is converted into a parallel beam of light by using a convex lens of short focal length and made to fall on an optically plane glass plate inclined at an angle of 45° to the vertical, where it gets reflected onto the Plano-convex lens. The wavelength of monochromatic light source is determined from the radii of the interference rings.


  • All the components including sodium lamp,microscope, power supply & optics are housed in single piece compact body.
  • Optical glass plate mounted at 45°.
  • Smooth moving collimating facility.
  • Quick adjustment, good quality, well defined distinct fringes.
