Smart Pack

  • Reduce Weight of Packaging Materials
  • Increase Usage of Recyclable Packing Materials
  • Improve Packing Integrity
  • Decrease Shipping Costs

Thorlabs' Smart Pack Initiative is aimed at waste minimization while still maintaining adequate protection for our products. By eliminating any unnecessary packaging, implementing packaging design changes, and utilizing eco-friendly packaging materials for our customers when possible, this initiative seeks to improve the environmental impact of our product packaging. Products listed above are now shipped in re-engineered packaging that minimizes the weight and the use of non-recyclable materials.b As we move through our product line, we will indicate re-engineered packages with our Smart Pack logo.

  • Travel-based emissions reduction calculations are estimated based on the total weight reduction of packaging materials used for all of 2013’s product sales, traveling 1,000 miles on an airplane, to provide general understanding of the impact of packaging material reduction. Calculations were made using the EPA’s shipping emissions values for different modes of transport.
  • Some Smart Pack products may show a negative weight reduction percentage as the substitution of greener packaging materials, such as the Greenwrap, at times slightly increases the weight of the product packaging.

Is there a way to put a stepper motor actuator on this product?

Hello, thank you for contacting Thorlabs. Yes, it is possible to install a stepper motor actuator (such as the ZST213B) in the CT1 since it has a 3/8" mounting barrel.

The description in the price box for the CT1 reads: 1/2" Cage Translation Stage. Please consider: 1/2" Travel 30mm Cage translator with CT101.

  • Comes with CT101 Ø1" Optic Mount for Optics up to 0.35" (8.9 mm) Thick
  • Precision Linear Ball Bearings
  • Lockable Design

The CT1 Cage Translator is designed to be used in 30 mm cage systems that require translation along the optical axis of the cage. Precision linear ball bearings are used to ensure smooth, high-resolution motion. The graduated micrometer provides 1/2" (12.7 mm) of linear translation and has 0.001" graduations. The smallest incremental movement of the carriage is approximately 1 µm. The included micrometer (Item # 148-811ST) may be switched out with a metric micrometer (Item # 148-801ST) with 10 µm graduations.

The modular design allows the accessories sold below to be mounted to the movable carriage of the CT1. As shown in the image, the CT1 stage includes the CT101 Ø1" Optic Mount, which has internal SM1 threading (1.035"-40) for mounting Ø1" optical components up to 0.35" thick, or externally SM1-threaded components, such as our SM1 lens tubes. One SM1RR retaining ring, two 4-40 and two M3 cap screws for securing the mount, and two removable dowel pins for alignment are also included with the mount.
