A vibration-isolated optical system is described comprising: (a) a generally enclosed optical transmission system including at least first and second light tubes and an enclosed control chamber connected to the light tubes; (b) optical beam control means within the chamber for controlling the path of an optical beam within the light tubes; (c) support means separate from the chamber and extending into the chamber mounting the control means therein; (d) first and second vibration isolation bellows respectively connecting the first and second light tubes to the chamber, the bellows each having an axis generally parallel to each light tube; (e) third vibration isolation bellows mounted between the support means and the chamber; (f) means for applying a vacuum to the chamber, the first, second and third bellows and the light tubes; and (g) means for applying a selected compressive force along the length of each of the first, second and third bellows for offsetting vacuum-generated loads in the bellows.
