Dovetail Translation Stages

Bar-Guided Micro-Translation Stages

Precision Translation Stages

High Precision Translation Stages

A translation stage is for linearly moving components such as optics and opto-mechanical components. There are various types of translation stages which their characteristics are dependent on thei translation structures. The table below lists our products of translation stages so customers can make selections according to their applications.

Dovetail Stages

Precise and smooth linear translation with no backlash is made possible by dovetailed guides and a spring-loaded micrometer (or lead screw mechanism). The springs pre-load the moving plate, eliminating the backlash. In the tables below "X" stands for 1-dimensional stage and "X-Y" stands for a combination of 2-dimensional. "A" indicates the micrometer mounted at the end (center drive) while "B" indicates the micrometer at the side (sidedrive).

The GCM-1112M Gimbal Base is a socket mounted platform with a high precision ball that offers free spherical motion over a complete hemisphere. A single locking mechanism provides reliable and rapid angular positioning of any component mounted on the base.
