The cage system uses three steel rods along a common optical axis. Optical components can be mounted, flexible to your individual purpose. A variety of holders are available for mounting mirrors, lens, polarizers, beam splitter cubes and C-mount cameras. Thorlabs provides an extensive selection. Optical Cage Systems are used to create optical setups in a variety of prototyping or university research applications. Optical Cage Systems are designed for modularity with. OptoSigma's CAGE Systems come in three (3) standard sizes, P16 (diameter: 4mm rods, 16mm pitch between the rods), P30 (diameter: 6mm rods, 30mm pitch between the rods) and P60 (diameter: 6mm rods, 60mm pitch between the rods).
