Optical Cages

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). Our systems are compatible with industry standards, though, our intent was to design and build cage systems that are more stable and accurate vs. others on the market today. A unique feature is the ability to place and remove individual components by “Dropping them In-Place” when 3-rods are utilized. This is highly unique and convenient. You can then add the 4th rod to finish the assembly. A large selection of accessories and adapters are available for integration into optical setups using mounting posts or lens tubes. Optic holders and accessories are supported by four (4) rigid steel rods (CAGES) to mount optical components along a common optical axis. In addition, the optic holders can split the optical axis and the cage into two or fold it to 90 degrees. The CAGE system has no distinction of orientation. Therefore, it is possible to place the holders in various orientations, which is convenient for constructing a three-dimensional optical system. Need help specifying components?

Optical Cage System Guide

What is a Optical cage system?

Optical cage system is different from normal optical system, which build on optical experiment table. （Its reference is optical experiment table.）

The cage system is build on four rods.（Its reference is optical axis.)

Features of products: Slot-in method

How to fix side-in type holder plate?

Rotate the holder plate using the rod as a fulcrum. (An arrow on the holder plate indicates the fulcrum).
Make sure that the two rods fit into the end of the slot on the holder plate.
By tightening the set screws, the holder plate is fixed to the rod (cage).
By attaching the fourth rod, it will be able to slide the holder plate along the rod without coming off.
