A light-translation system (10) includes a fixed base (15,16) and translatable mirror mount (23,24) having mirror-supporting brackets (110,114). A first and second arm (27,28) are pivotally attached in parallel, spaced-apart relation adjacent first ends to the base and adjacent second ends to the mirror mount to form a parallelogram-shaped attachment with the base and mirror mount. The pivotal attachments are formed using flexural pivots (63), each having a thick portion (64,65) oriented for achieving minimal angular deviation of the mirror (11). A first bracket (110) has three pads (111,112,113) for supporting one side (104) of the mirror. A second bracket (114) has two surfaces (115,116) shaped to support an edge (109) of the mirror, each surface positioned opposite a pad. A washer (119) dimensioned to admit a mounting screw (117) is positionable opposite a third pad (113) against an outside wall (118) of the mirror mount to removably retain the mirror without imposing appreciable bending stress thereon. <IMAGE> |
