Lens Tube, 2 inch dia. LT Series, 3 inch length

The LT20-30 Lens Tube provides a means to mount multiple lenses into a single holder. The 3 inch (76.2 mm) long 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. 2 inch (50.8 mm) diameter lenses are held in place with threaded retaining rings. One retaining ring is included with each lens tube.

Ideal for Fast Prototyping of Complex Lens Systems

Lens Tubes allow the combining of several optical components into stable and rigid assemblies and are used to create beam expanders, telescopes, microscopes, collimators and more.
