Slotted Lens Tube SM2L100-E
JCOPTIX slotted lens tubes use a double-layer structure with two slots in each tube wall, enabling adjustment of optic positions without disassembly. The outer sleeve rotates smoothly through 360° without play. Opening the sleeve allows axial lens adjustment; closing it afterward blocks ambient light from the optical path. The tubes accept Ø12.7 mm, Ø25.4 mm, or Ø50.8 mm optics. Two internal retaining rings secure and separate optics at any internal position. JCOPTIX also offers standard SM05, SM1, and SM2 lens tubes and matching adapters, retaining rings, and spanner wrenches. SM05 slotted lens tubes: SM05 internal/external threads; slotted walls for easy positioning; two retaining rings secure optics; accept Ø12.7 mm optics. The JCOPTIX SM05 outer sleeve rotates smoothly through 360° without play. Mainly for Ø12.7 mm optics, each tube includes two SM05RR rings. Lenses can be adjusted through the slots without removing the rings; rotating the outer sleeve afterward covers the slots to block light. SM1 slotted lens tubes: SM1 internal/external threads; slotted walls for easy positioning; two retaining rings secure optics; accept Ø25.4 mm optics. The JCOPTIX SM1 outer sleeve rotates smoothly through 360° without play. Mainly for Ø25.4 mm optics, each tube includes two SM1RR rings. Adjust lenses through the slots without unscrewing the rings, then rotate the outer sleeve to cover the slots and block light. SM2 slotted lens tubes: SM2 internal/external threads; slotted walls for easy positioning; two retaining rings secure optics; accept Ø50.8 mm optics. The JCOPTIX SM2 outer sleeve rotates smoothly through 360° without play. Mainly for Ø50.8 mm optics, each tube includes two SM2RR rings. Adjust lenses through the slots without unscrewing the rings, then rotate the outer sleeve to cover the slots and block light.
