Advanced Optomechatronic Systems

FSO Instruments specializes in making advanced optical systems for laser satellite communication, both in ground stations and satellites. These ‘optical benches’ are optomechatronic masterpieces that transmit and receive laser signals with high accuracy. Under the Resolite brand name, we offer several models, labelled with a number that refers to the diameter of the aperture in millimeters.
