    Cage System Tubes

    Cage System Tubes are used to cover portions of a TECHSPEC Optical Cage System. Cage System Tubes are designed to fit within the inner diameter of cage system plates in order to isolate the work environment from outside interference. Cage System Tubes may be used to protect a beam assembly from contamination or to prevent portions of a setup from being seen. A selection of breadboard adapters is also available for interfacing with optical breadboards.
