Michaelson Interferometer.

Michaelson Interferometer.

Michaelson Interferometer.

This new twist on the Michelson-Morley device measures the small differences in time needed for two separate light beams to travel two different paths. An interference pattern is produced by splitting a beam of light into two paths, bouncing the beams back and recombining them. The different paths may be of different lengths or composed of different materials to create alternating interference fringes on a screen. Positioning the magnetic optical components on our metal base is easy and accurate. The distance can be adjusted without a ruler as the base contains a permanent grid at a 45° angle. Unlike other models, we include all parts needed to measure the coefficient of linear expansion of a metal. Includes: red laser pointer; metal base with scale; optical components with magnets; 3 rods: brass, aluminum, steel; and our special diffraction grating which separates light into two points.
