Optical System & Interferometers
Components

An optical unit consists of various components.
You can assemble a different optical unit or change the configuration of the unit according to the purpose of an experiment by purchasing additional components. (For example, replacing the screen component with the imaging lens and camera components enables loading of observed images.)
In addition, we offer variety of components required for optical adjustment and safety control.
