Optical lens adapter LHT-MD

There are three sizes of Nesting Lens Tube groups, large, medium and small, to cover the main lens diameters. The medium size (34mm) along with the lens cells covers lenses with diameters 25.4 and 30mm. All three sizes of lens tubes, 20, 34, and 56mm, can be connected together. 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 medium-sized lenses including 50 and 50.8mm lenses ◦There are adaptors allowing smaller lens cells to be used within larger lens tubes.
