LT-series Lens Tubes provide a means to mount multiple lenses into a single holder. Each lens tube has an internal thread on one end and a mating external thread on the other. This allows them to be connected together end-to-end to provide endless configurations. Lenses are held in place with threaded retaining rings and one ring is included with each lens tube.
