Features
The adapters sold below offer a way to switch between 16 mm and 30 mm cage systems or 30 mm and 60 mm cage systems. The SP05(/M), LCP6X, and LCP02(/M) adapters each have eight through holes for cage rods, which are secured in the plate using 4-40 or M4 x 0.7 setscrews. The LCP4S has four outer through holes for 60 mm cage rods, which are secured with 4-40 setscrews, and four inner counterbored holes for 30 mm cage compatability. We also offer orthogonal cage system size adapters. Cage System OverviewThe 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 StandardsThorlabs 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. Standard ThreadsThe 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. ![]() An example of the standard cage plate measurements determining cage system compatibility.

The SP05(/M) cage plate provides a convenient means for coupling 16 mm and 30 mm cage assemblies (see image to the right). The Ø4 mm SR rod and Ø6 mm ER rod holes are each accompanied by a side-located locking 4-40 setscrew, which can be secured using a 0.05" hex key. The SP05(/M) also has an 8-32 (M4) tapped hole for post-mounting and a centered SM05 (0.535"-40) tapped bore (SM05RR retaining rings sold separately). This cage plate offers tight tolerances on the cage rod holes to ensure that both the 30 mm and 16 mm cage segments are centered around the central SM05 bore. Additionally, two of these cage plates can be used to straddle a 16 mm cage subassembly in such a way that the entire assembly [SP05(/M), 16 mm subsystem, and SP05(/M)] can slide along the 30 mm cage rods as a single optomechanical unit. For users who do not need the tight tolerances necessary to accommodate both 16 mm and 30 mm cage rods, Thorlabs offers a 30 mm cage plate, the CP32(/M), for mounting a Ø1/2" optic or lens tube. ![]() ![]() Click to Enlarge LCP4S Adapter Mounted to Quantalux® sCMOS Camera for Compatibility with 60 mm Cage Components. Note the LCP4S adapter has counterbored holes for 30 mm cage compatibility and through holes for 60 mm cage compatibility.
The LCP4S Cage Plate Adapter provides a convenient means for coupling 30 mm and 60 mm cage assemblies via our Ø6 mm ER cage rods. The thin 4 mm (0.16") profile of this adapter is ideal for situations where axial space is limited. The centered SM1 (1.035"-40) tapped hole is compatible with our SM1-threaded lens tubes. Each of the outer through holes for 60 mm cage compatability is accompanied by a side-located locking 4-40 setscrew, which can be secured using a 0.05" (1.3 mm) hex key. The four inner holes for 30 mm cage compatability are counterbored for use with 4-40 x 3/16'' cap screws which are sold seperately (SH4S019 recomended). Unlike the LCP02(/M) cage plate adapters, this adapter does not have a tapped hole for post mounting due to the thin profile. Additionally, this cage plate adapter facilitates the mounting of our compact scientific cameras on 60 mm cage components (see image to the right). For example, our 2CM2 Two-Camera Mount for Microscopes incorporates two LCP4S adapters. The thin profile of the adapter is required to position the image plane of the cameras within the adjustable focus range of the mount. ![]() ![]() Click to Enlarge LCP6X Adapter Mounted to a Zelux™ CMOS Compact Camera for Compatibility with 60 mm Cage Components
The LCP6X Cage Plate Adapter provides a convenient means for coupling 30 mm and 60 mm cage assemblies via our Ø6 mm ER cage rods. The centered SM1-threaded (1.035"-40) hole is compatible with SM1-threaded lens tubes or Ø1" optics up to 0.08" (2 mm) thick (SM1RR retaining rings sold separately). Each cage rod through hole is accompanied by a side-located locking M4 x 0.7 setscrew that can be adjusted using a 5/64" (2 mm) hex key. These setscrews provide improved stability for attaching cage rods compared to the 4-40 setscrews used in the LCP4S cage plate adapter (sold above). Unlike the LCP02(/M) cage plate adapter, this cage plate adapter does not have a tapped hole for post mounting due to the thin profile. Similar to the LCP4S adapter, the LCP6X adapter can facilitate the mounting of our compact scientific cameras on 60 mm cage components, as seen in the image to the right. ![]()
The LCP02(/M) Cage Plate provides a convenient means for coupling 30 mm and 60 mm cage assemblies via our Ø6 mm ER Cage Rods. The centered SM1 (1.035"-40) tapped hole directly accepts optics up to 0.35" (9 mm) thick (SM1RR retaining rings sold separately). 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. The LCP02(/M) also has an 8-32 (M4) tapped hole for Ø1/2" post mounting. The surface with the Additionally, two of these cage plates can be used to straddle a 30 mm cage subassembly in such a way that the entire assembly [LCP02(/M), 30 mm subsystem, and LCP02(/M)] can slide along the 60 mm cage rods as a single optomechanical unit. A 16 mm cage assembly can also be easily integrated by utilizing the SP05 cage plate adapter (sold above). | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
