9012[X] - Michelson Interferometer


The Michelson Interferometer reference design is part of the 3DOptix Interferometer design series. Interferometers use the property of interference between two optical beams to accurately measure various optical properties. 3DOptix provides an easy and precise manner in which to build such devices.

The Michelson interferometer uses a beam-splitter, which is a partially transmissive mirror that divides an optical beam into two separate arms. The beam splitter is used to split and to recombine the optical beam. The difference between the path lengths of the two arms affect the interference pattern and can be adjusted by accurately moving one of the mirrors.

Our reference designs include the 3DOptix building-blocks, which are based on the BreadBox™ platform and its modular and versatile optomechanical mounts and adaptors. The 3DOptix devices are modular and very robust. Once the reference designs are assembled they can be moved around as a unit while maintaining the accuracy of the device.

The following design is for optical elements of Ø1"/25mm. With the following easy-to-use instruction manual and its associated instructional video, you can focus on the experiments and not on the alignments.
