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.

Smart Pack

• Minimize CO₂ Footprint
• Reduce Non-Recyclable Packing Materials
• Improve Packaging Integrity
• Saves on Shipping Costs

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.

Over the course of a year, the re-engineered packaging across our product line is projected to reduce our CO₂ footprint by more than 16,184 kg and reduce packaging by over 13,893 pounds! As we move through our product line, we will label re-engineered packages with our green Smart Pack sticker (above).

• Coarse Rotation: 360° Continuously Adjustable
• Graduations: 2° Increments
• Directly Mounts Ø1/2" Optics up to 7.3 mm (0.29") Thick
• Beam Height: 0.72" (18 mm) to Center of Cage
• Runout: <0.0001" (25 μm) Along Optical Axis
• Max. Clear Aperture: 0.43"
• Lockable design

The CT104 rotation mount provides 360° of continuous rotation for Ø1/2" and SM05 threaded components. The 2° graduation allows for precise positioning of components, such as linear polarizers and waveplates. A top-mounted nylon-tip setscrew is used to lock the freedom of rotation when the mount has been set in the correct orientation. The CT104 is compatible with our CT1 cage translator and MS series translation stages. One SM05RR retaining ring is included with each unit.
