Features

Vertically Mount a Cage System to an Optical Table
16 mm, 30 mm, and 60 mm Cage System Compatible Options
Counterbored Slots for Mounting to Imperial and Metric Breadboards

These black-anodized aluminum mounting plates allow a cage system to be mounted vertically on an optical table surface. Each plate can be attached to an optical table using counterbored slots or holes, making them compatible with metric and imperial tables and breadboards.

The CPVMP2 and CPVMP2 vertical cage system mounting plates are compatible with either 16 mm and 30 mm (Item # CPVMP2) or 30 mm and 60 mm (Item # CPVMP) cage systems. The CPVMP2 plate has a footprint of 2.63" x 1.60" (66.8 mm x 40.6 mm) and the CPVMP plate has a footprint of 3.60" x 2.80" (91.4 mm x 71.1 mm). These plates use through holes with side-located M4 x 0.7 locking setscrews to attach cage rods for our cage systems. A center-located internally SM05-threaded through hole allows the use of our line of externally SM05-threaded components with the CPVMP2 plate, while the center-located internally SM1-threaded through hole of the CPVMP plate allows the use of our line of externally SM1-threaded components.

We also offer UBP Series Universal Base Plates with options for mounting 16 mm, 30 mm, and 60 mm cage systems. Cage rods are attached to these plates using 4-40 tapped holes. A center-located counterbored slot on each plate allows for rotation and translation of the plate. An array of threaded and counterbored mounting holes are also available for mounting other optical components, such as our optical post assemblies. Please see below for details and an application shot showing a 30 mm cage system vertically mounted using the UBP2 base plate.

Dual-Height Beam Director

The CPVMP Vertical Mounting Plate can be used to construct vertical cage systems on both imperial and metric breadboards. Figure 2.1 depicts a dual-height beam director mounted to an optical table with the CPVMP.

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 Figure 14A). 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.

Figure 14A An example of the standard cage plate measurements determining cage system compatibility.

Standard Cage System Measurements
Cage System	16 mm	30 mm	60 mm
Thread Series	SM05	SM1	SM2
Rod to Rod Spacing	16 mm (0.63")	30 mm (1.18")	60 mm (2.36")
Total Length	25 mm (0.98")	41 mm (1.60")	71.1 mm (2.80")

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. Explore our Cage Systems Visual Navigation Guide to see the full range of Thorlabs' cage components.

Also, could the counterbore slots be slighlty extended (ideally by 12 mm)?

Thank you for contacting Thorlabs. We have reached out to you directly to discuss the feasibility of this request. As mentioned below, you may reach out directly to techsales@thorlabs.com for future customized item requests.

Hi, Would there be a way to get an unanodized version of the CPVMP (ie vacuum-compatible)?

jdelia (posted 2024-09-13 09:36:16.0)

Thank you for contacting Thorlabs. This is something we would be able to offer as a customized item. We have contacted you directly to discuss this further. For future reference, you may reach out to techsales@thorlabs.com to request a custom part.

Is it possible to build a 60 mm cage system by using two UBP2 units placed side by side instead of CPVMP? Since the delivery of the latter is taking so long, I have to find an alternative. Thanks

Thank you for contacting Thorlabs. Unfortunately, the 4-40 tapped holes would not line up properly using this configuration. I have contacted you directly regarding alternative solutions.

Orientation is not adjustable, right? and two rings can not be hidden as does not look like in the picture???

Response from Jeremy at Thorlabs: Both the C4W and LCP02 have internal SM1 thread. Therefore, you just need to screw in the SM1T2 to the C4W and then screw the LCP02 onto the SM1T2.

How will SM1T2 be used to Attach the C4W Cage Cube and LCP02 Cage Plate Adapter?

Vertically Mount Cage Systems to an Optical Table
Centered SM-Threaded Mounting Hole
Counterbored Slots for Mounting to Imperial and Metric Breadboards

These vertical mounting plates mount cage systems vertically on an optical table surface. The CPVMP2 plate is compatible with 16 mm and 30 mm cage systems and also offers a central SM05-threaded bore, while the CPVMP plate is compatible with 30 mm and 60 mm cage systems and has a central SM1-threaded bore. Side-located, counterbored slots can be used to securely mount the plate onto either an imperial or metric breadboard.

The SR rods (16 mm cage systems) and ER rods (30 mm and 60 mm cage systems) are held in place by eight side-located M4 x 0.7 setscrews: the four screws for the inner cage rods are inset into the side of each plate, while the four visible setscrews are for the outer cage rods.

Universal Base Plates

Six Variants Offered with a Wide Variety of Mounting Options
Central Counterbored Slot Allows for Rotation and Translation
Models Available for 16 mm, 30 mm, and 60 mm Cage System Mounting

Our UBP Series Universal Base Plates increase the flexibility of any optical setup by providing mounting holes in virtually any orientation on an optical table or breadboard. This freedom allows users to mount various components or stages in a wide array of orientations outside of what is dictated by the standard 1" (25.0 mm) hole pattern. The counterbores in these plates also allow users to adapt metric components to an imperial optical table and vice versa.

Refer to Table 208A for specifications and detailed mounting options, including mechanical drawings. Each base plate has a counterbored slot in the center for mounting flexibility at any rotation, as well as counterbored holes at the corners for mounting to compatible breadboards. Cage system compatibility is offered via 4-40 tapped holes with the appropriate spacings.
