Features
The 30 mm cage cube plates offered here are ideal platforms for building light-tight cage cube systems. Our B1C(/M) and B2C Cage Cube Plates are compatible with Thorlabs' 30 mm Cage Cubes and accessories. The B1C Blank Plate can be used to create a light-tight environment within the C4W or C6W cage cubes. The B2C SM1-Threaded Plate provides an additional SM1-threaded port on the top or bottom of our C4W or C6W cage cubes. Thorlabs offers a wide and growing complement of accessories for 30 mm cage cubes, including optic mounts, platforms, and rotating platforms. These tools provide a complete family of versatile building blocks suited for virtually any 30 mm cage cube optomechanical setup. 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 B1C(/M) is a blank cover plate that is designed for the C4W and C6W Cage Cubes. The top has a rubber o-ring that creates a light-tight seal, while the bottom, pictured to the left, has a centered 8-32 (M4) tapped hole for mounting purposes. The B1C(/M) ships with four 4-40 cap screws (3/32" hex). ![]()
The B2C is an internally SM1-threaded (1.035"-40) cover plate, which allows components in SM1-threaded mounts to mate to the cube. This plate is designed for use with our C4W and C6W Cage Cubes. The B2C(/M) ships with four 4-40 cap screws (3/32" hex). | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
