An active alignment machine includes a base, a first pillar, a second pillar, a distribution module, a first alignment module, a second alignment module and a third alignment module. The first pillar has a first pillar top surface. The second pillar has a second pillar top surface. The first pillar top surface and the second pillar top surface cooperatively support plural assembling specifications. The distribution module is installed on the base and arranged between the first pillar and the second pillar. The first alignment module, the second alignment module and third alignment module are replaceable to be assembled with or dissembled from the first pillar top surface and the second pillar top surface. The first alignment module, the second alignment module and third alignment module work with the distribution module to perform the active alignment on a first-type product, a second-type product and a third-type product, respectively.

A bipod flexure mount couples an optic to a base while isolating the optic from strain to resist wavefront error. The bipod flexure mount has a distal attachment pad to be coupled to the optic and a proximal attachment pad to be coupled to the base. A pair of beams extend between and couple the distal and proximal attachment pads. The distal attachment pad, the proximal attachment pad and the pair of beams are disposed in and define a planar layer with opposite planar surfaces that are substantially parallel. The bipod flexure mount is relatively flexible about four degrees of freedom and is relatively stiff about two degrees of freedom.

An optical element driving mechanism is provided and includes a movable portion and a fixed portion. The movable portion includes a carrier for carrying an optical member with a first optical axis. The fixed portion has a top surface, a first side surface and a second side surface. The top surface extends in a direction that is parallel to the first optical axis. The first side surface and the second side surface extend in a direction that is not parallel to the first optical axis from the edge of the top surface and face different sides of the optical member. The shortest distance between the optical member and the first side surface is shorter than the shortest distance between the optical member and the second side surface.
