XY Translation Mounts for 16 mm Cage Systems
XY Translation Mount
Slip Plate Positioner
SCP05T with Ø1/2" Lens Tubes for Light-Tight Applications
Thorlabs offers three XY mounts for the 16 mm cage system. The SCP05 and SCP05T XY Translation Mounts each hold a Ø1/2" (Ø12.7 mm) optic using the included SM05RR retaining ring and offer fine XY adjustment. The SSP05 Slip Plate Positioner offers coarse XY adjustment of a Ø1/2" optic.
Cage System Compatibility: Thorlabs offers 16 mm, 30 mm, and 60 mm cage systems designed for Ø1/2", Ø1", and Ø2" optical components, respectively. The parts on this page are compatible with our 16 mm cage system and utilize Ø4 mm SR cage rods.
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 accomodate 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.
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.

SCP05 and SCP05T
Thorlabs' SCP05 and SCP05T XY translating lens mounts provide ±1.0 mm (±0.04") of travel perpendicular to the optical axis of a 16 mm cage system. The adjusters feature 100 threads per inch and provide 250 μm of translation per revolution. The adjusters may be actuated by hand or using a 5/64" (2.0 mm) hex key or balldriver and the setscrews for mounting cage rods offer a 0.05" (1.3 mm) hex.
The SCP05 and SCP05T mounts both contain internal SM05 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 the retaining lip built into the SM05-threaded carriage. Additionally, the SCP05T mount contains internal SM05 threads on the front and rear faces of the housing (as illustrated in the diagram above), allowing light-tight connections to our Ø1/2" lens tubes. (The SCP05 is only threaded on the rear face.)
To remove/install the SM05RR retaining ring or an optic, the adapter retaining ring on the front of the mount must first be removed using an SPW801 Spanner Wrench. For reference, please see the animation above and to the right.
Thorlabs' SSP05 16 mm Slip Plate Positioner is designed to provide coarse XY positioning of optical components within our cage assembly system. The component that provides position adjustment is the movable carriage, which moves along the surface of the other plate for small XY adjustment. The movable carriage provides manual adjustment only and is best utilized in conjunction with an alignment laser to monitor centricity.
Adjustment is achieved by first loosening the two 2-56 button-head adjustment screws with a 0.05" (1.3 mm) hex key or balldriver, manually adjusting the movable carriage in the desired position, and then tightening the screws to lock the carriage in place. The movable carriage is internally SM05 threaded and compatible with our Ø1/2" lens tubes, which can be used to hold Ø1/2" optics. Each cage rod through hole is accompanied by a side-located locking 4-40 setscrew, which can be secured using a 0.05" (1.3 mm) hex key or balldriver.
