Labjacks are a convenient way of providing a large range of vertical travel for the alignment of a laser or sub-system. The bottom plate is secured to the base and the top platform provides a new baseplate for the device to be elevated. Rotation of the knob projecting from the end of the labjack elevates the platform while holding it parallel to the base. Quite heavy loads can be mounted on these labjacks and then positioned to a surprisingly high level of accuracy. Labjacks are extremely useful for making up height differences during the set up of an optical system. Oversize platforms threaded with 1/4-20 or M6 holes are also offered to provide for handling larger or more complex optical systems.
