Mechanics for Alignment
Hardware for mounting and aligning the CGH test.
Alignment Stages
AOM Fine Positioner Mounts (FPM) allow quick and easy setup and operation of CGHs. The FPM allows fine adjustment of all 6 degrees of freedom.
All standard CGHs can be precision bonded into a cell that interface with the mount using easy “click-in” magnetic coupling.

Alignment References
AOM provides references for aligning the CGH and the Unit Under Test (UUT). The details depend on customer requirements of datum references and alignment procedures. Some examples of mechanical alignment product offerings are illustrated below.
Opto-Mechanical References Attached to the CGH
Standard fittings can be attached to the CGH to support tooling balls or optical references to enable quick and accurate assembly and alignment. The position of these features can be controlled to 1 micron accuracy at user specified locations.
Opto-Mechanical References (SMRs) Attached to the Unit Under Test
Metrology Platform
The metrology platform is a solution for quick and repeatable measurements of batches of optics using a CGH. The platform is coupled to CGH in a one-time alignment step, providing a kinematic interface to the Unit Under Test (UUT).
