Patent ID: 7817890

Claim:
A mechanical nanomover for optical elements alignment, comprising: a platform ( 100 ) having an upper surface ( 101 ) and a lower surface ( 102 ); a front supporting block ( 201 ) and a rear supporting block 202 firmly installed upon the upper surface ( 101 ) of the platform 100 ; the front supporting block ( 201 ) and the rear supporting block ( 202 ) being retained with a distance for receiving other elements; a right metal sheet ( 301 ) and a left metal sheet ( 302 ) arranged between and firmly secured the front supporting block ( 201 ) and the rear supporting block ( 202 ); and the right metal sheet ( 301 ) being spaced from the left metal sheet ( 302 ); the right metal sheet ( 301 ) and the left metal sheet ( 302 ) being not contact with any surface of the platform ( 100 ); and the right metal sheet 301 and left metal sheet 302 are deformable; a movable block ( 400 ) being firmly secured between the right metal sheet ( 301 ) and left metal sheet ( 302 ); a lower surface of the movable block ( 400 ) being spaced from the upper surface ( 101 ) of the platform ( 100 ); the movable block ( 400 ), right metal sheet ( 301 ) and left metal sheet ( 302 ) being combined as a rigid structure, a first rod 501 being connected to a lower surface ( 401 ) of the movable block ( 400 ); a weak spring ( 601 ) having a middle section connected to the first rod ( 501 ); the weak spring ( 601 ) has a small elastic coefficient K 1 ; a strong spring ( 602 ) having two ends which are firmly secured to the front supporting block ( 201 ) and rear supporting block ( 202 ); a middle section of the strong spring ( 602 ) being contact to the right metal sheet ( 301 ); the strong spring ( 602 ) having a large elastic coefficient K 2 ; the large elastic coefficient K 2 being much greater than the small elastic coefficient K 1 ; and a driving unit ( 700 ) having one end connected to another end of the weak spring ( 601 ); adjustment of the driving unit ( 700 ) will compress or expanding the weak spring ( 601 ).
