Michelson Interferometer

Function and Applications

For measuring light wavelengths and refractive indices of liquids and gases.

Benefits

• Precise determination of the wavelength of monochromatic light
• Capability to determine coherence lengths using spectral lamps and filters
• Determination of refractive indices of liquids, air, and other gases
• Very fine mirror displacement via micrometer screw (1 µm per division)
• High accuracy of wavelength measurement (relative error approx. 0.5%)

Technical Specification

• Two front-surface plane mirrors and one semi-transparent mirror mounted on a metal plate
• Mirror displacement with 0.001 mm resolution using micrometer screw and 1:10 lever reduction
• Fine adjustments for tilt alignment of the fixed mirror
• Holder for an additional cuvette required for gas investigations
• Base plate: 120 × 120 mm
• Mirror surfaces: 30 × 30 mm
• Includes protective cover and 2 mounting rods
