Lens Tube, 20mm Lens, 50mm Long

LHT-20T-50

The small size lens tubes (20mm) along with the lens cells covers lenses with diameters 10, 12.7, 15 and 20mm. Lens cells are used within lens tubes to allow adjustment of lens groups simultaneously. They also allow small optics to be easily mounted in the same lens tube with larger optics. The threads used with the Nesting Lens Tube family are common to other OptoSigma optomechanical hardware allow mixing of tube mounted optics with existing mounts and optic holders.
◦Lens tubes allow rigid mounting of multiple optical elements along a fixed axis. LHT series lens tubes have optional lens cells that thread into the main tube allowing focusing movement of lens groups within the lens cell.
◦These Nesting Lens Tubes can mount smaller lenses including 10, 12.7, 15, and 20mm lenses
◦There are adaptors allowing smaller lens cells to be used within larger lens tubes.
