The CT1 Cage Translator is designed to be utilized within 30 mm cage systems (see image to right) requiring translation along the optical axis of the cage. A modular design approach has been taken to allow a series of accessories to be mounted to the movable carriage of the CT1 (see below).
Precision linear ball bearings are used to ensure smooth high resolution motion. A graduated micrometer provides 1/2" (12.7 mm) of linear translation and has 10 µm (0.001") graduations. The smallest incremental movement of the carriage is approximately 1 µm. One SM1RR retaining ring is included with each unit.

Thorlabs' Green Initiative is aimed at reducing waste. To that end, we have begun to re-engineer our product packaging. The CT1 is now shipped in re-engineered packaging that minimizes the use of non-recyclable materials.
