| The cage system uses four rigid steel rods on which optical components can be mounted along a common optical axis. The cage system is available in three sizes where the rods are located on the corners of a 16 mm, 30 mm, or 60 mm square. Thorlabs provides an extensive selection of accessories for the cage system as well as adapters that allow the user to switch back and forth between the three different cage rod spacings offered. In addition, the cage system can be integrated into optical setups using mounting posts and/or lens tubes. |
