Product Family Description

TECHSPEC® Cage System Linear Translation Assemblies are used to add linear translation to a TECHSPEC Optical Cage System setup. The built-in translation assembly enables coarse positioning along the cage rods. Once fixed to the cage rods, fine translation can be done using a micrometer drive. By adding additional springs and replacing the 3mm x 50mm rods (#85-470) with two 3mm x 75mm (#86-847, sold separately), the ½" standard travel can be extended to 1". TECHSPEC Cage System Linear Translation Assemblies are available in two options: simple translation utilizes 6mm rods and standard plates, while ball bearing translation utilizes ball bearing slides for low-friction translation.

Note: Micrometer/drive mechanism and 6mm Support Rods sold separately.
