Thorlabs' MCXY05(/M) Translation Mount provides ±1.0 mm (±0.04") of X and Y travel for Ø1/2" optics. The front and back plate of the mount are stationary, while the inner carriage can move in the X and Y directions in the plane perpendicular to the optical axis. The adjusters provide 200 µm translation per revolution and may be actuated by hand or using a 0.05" (1.3 mm) hex key or balldriver. A 4-40 (M3 x 0.5) mounting hole located on the bottom of the mount allows it to be mounted on our Mini-Series Posts. Additionally, four through holes with 0.05" (1.3 mm) hex setscrews accept Ø4 mm cage rods for compatibility with our 16 mm cage systems. If replacement setscrews are needed, we offer SS4B013 brass setscrews, which use a 0.05" (1.3 mm) hex.

The MCXY05(/M) mount contains internal SM05 (0.535"-40) threads suitable for mounting Ø1/2" (12.7 mm) optics up to 0.23" (5.8 mm) thick using the included SM05RR retaining ring. The optic is held in place by the retaining ring and a retaining lip built into the SM05-threaded carriage. The center of the optic carriage is 0.89" (22.7 mm) above the base of the mount when the carriage is centered. Thorlabs' SPW603, SPW603L, or SPW801 Spanner Wrenches can be used to tighten or remove the SM05RR retaining ring.

Cage System Overview

The Cage Assembly System provides a convenient way to construct large optomechanical systems with an established line of precision-machined building blocks designed for high flexibility and accurate alignment.

16 mm, 30 mm, and 60 mm Cage System Standards

Thorlabs offers three standards defined by the center-to-center spacing of the cage assembly rods (see image below). The 16 mm cage, 30 mm cage, and 60 mm cage standards are designed to accommodate Ø1/2", Ø1", and Ø2" optics, respectively. Specialized cage plates that allow smaller optics to be directly inserted into our larger cage systems are also available.

Standard Threads

The flexibility of our Cage Assembly System stems from well-defined mounting and thread standards designed to directly interface with a wide range of specialized products. The three most prevalent thread standards are our SM05 Series (0.535"-40 thread), SM1 Series (1.035"-40 thread), and SM2 Series (2.035"-40 thread), all of which were defined to house the industry's most common optic sizes. Essential building blocks, such as our popular lens tubes, directly interface to these standards.

Cage Components
Cage Rods 16 mm These rods are used to connect cage plates, optic mounts, and other components in the cage system. The SR Series Cage Rods are compatible with our 16 mm cage systems, while the 30 mm and 60 mm cage systems use ER Series Cage Rods.
30 mm
60 mm
Cage Plates 16 mm These serve as the basic building blocks for a cage system. They may have SM-threaded central bores, smooth bores sized for industry standard optics or to accommodate the outer profile of our SM Series Lens Tubes, or specialized bores for other components such as our FiberPorts.
30 mm
60 mm
Optic Mounts 16 mm Thorlabs offers fixed, kinematic, rotation, and translation mounts specifically designed for our Cage Systems.
30 mm
60 mm
Cage Cubes 16 mm These cubes are useful for housing larger optical components, such as prisms or mirrors, or optics that need to sit at an angle to the beam path, such as beamsplitters. Our cage cubes are available empty or with pre-mounted optics.
30 mm
60 mm
Replacement Setscrews Replacement setscrews are offered for our 16 mm (SS4B013, SS4B025, and SS4B038) and 30 mm (SS4MS5 and SS4MS4) cage systems products.
Post and Breadboard Mounts and Adapters Mounting options for cage systems can be found on our Cage System Construction pages. Cage Systems can be mounted either parallel or perpendicular to the table surface.
Size Adapters Cage System Size Adapters can be used to integrate components from different cage system and threading standards.
Specialized Components Thorlabs also produces specialized cage components, such as Filter Wheels, a HeNe Laser Mount, and a FiberPort Cage Plate Adapter, allowing a wide range of our products to be integrated into cage-mounted optical systems.
