September 19, 2012, Barrington, NJ USA — Edmund Optics® (EO), the premier provider of optical components, introduces new TECHSPEC Cage System Linear Translation Assemblies. Offering a high precision alternative to complex optical alignment systems, these versatile opto-mechanical systems are designed for modularity and flexibility. TECHSPEC Optical Cage Systems consist of precision rods and plates, allowing the user to construct custom, adaptable opto-mechanical component systems with limitless options for modification, several of which are detailed below.

Linear Translation Assemblies
TECHSPEC Cage System Linear Translation Assemblies can add linear translation to TECHSPEC Optical Cage Systems setups. They are available in simple translation, using 6 mm rods and standard plates and ball bearing translation, with ball bearing slides for low-friction translation. The compact design is configurable for 1/2-inch or 1-inch travel and fine translation cane be achieved with the addition of micrometer drive.

Michelson Interferometer
The TECHSPEC Optical Cage System is an ideal solution for creating a Michelson Interferometer because, with the cage system rods supporting the structure, only minimal alignment is needed in the optics’ tip-tilt and in the distance between the two mirrors and the beamsplitter. “With a typical Michelson Interferometer set-up designed on a breadboard, precision alignment is crucial, but difficult to achieve. The compact, user-friendly Optical Cage System allows for easy adjustment of all the instrument’s parameters, from a linear micrometer to adjust the path length difference to a three knob tip-tilt mount to align the mirrors - all while using fewer parts,” said Amr Khalil, Product Line Manager, Edmund Optics.

Digital Video Microscope
A customized digital fluorescence microscope can be built with TECHSPEC Optical Cage System components, allowing the user limitless customization options with a simpler assembly. Magnification can be modified by changing objectives and interchangeable filter holders make swapping filters easy. Custom illumination and a spectrometer may also be added.

Using the TECHSPEC Optical Cage System makes alignment simple and easy. An autocollimator can be assembled and aligned in just a few short steps. Optics can be easily swapped out, which allows the user to quickly change the field of view and resolution. A camera may also be added in place of the eyepiece for image capture or video capability.

Optical Cage System saves time and money
Ideal for prototyping and demonstration applications, TECHSPEC Optical Cage Systems are highly durable and feature tight tolerances, excellent rigidity and exceptional flexibility. They offer the best price-to-performance ratio on the market, while guaranteeing smooth movement, precision alignment and excellent accuracy. TECHSPEC Optical Cage System Components are in-stock and available for immediate delivery. Detailed information, including products, applications, and videos can be found at
