Patent attributes
A mechanical nanomover for optical elements alignment comprises a platform; a front supporting block and a rear supporting block; a left metal sheet and a right metal sheet installed between the two supporting blocks; a movable block installed between the two metal sheets; a weak spring and a strong spring which are interacted with the movable block. A translation stage serves to drive the weak spring to drive the movable block. The elastic coefficient of the strong spring is much greater than that of the weak spring so that the larger displacement of the weak spring will induce only a small displacement of the movable block due to the interaction of the strong spring. No electric power is needed to drive the structure of the nanomover. The mechanical nanometer can provide a sufficient precision to the operation, while it is very inexpensive.
