Optical EngineeringLow-cost adjustable mirror mount
|Format||Member Price||Non-Member Price|
Complex optical systems commonly employ adjustable optical mounts for alignment purposes. The design of a low-cost adjustable mirror mount that provides simple tilt and height adjustments is described. This mirror mount employs conventional machining and standard off-the-shelf hardware and is, therefore, very suitable for low-cost rapid prototyping applications. A diamond-machined metal mirror is directly assembled to the mount with three screws and two precision dowel pins. The adjustments are provided by three spring-loaded screws between the mount and a fixed base plate. Two set screws are used for locking purposes after the adjustments have been made.
