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.

Stray Light Block Component IFC2-BD
Catalog CodeӤW1015

Reflected light from the reverse side of a half mirror or multiple-reflected light
inside an interferometer sometimes spread out of a laboratory bench as stray light.
This component safely blocks such optical paths.
It can also be used as a filter since an absorptive ND filter is used.
