Adjustable Lens Tube SM05L12-V

JCOPTIX rotationally adjustable lens tubes precisely position optics and finely adjust the first/last lenses in systems. Optics slide precisely in the tube and lock at the optimum position. The source introduces three steps: first, secure optics in the internal threads using the supplied SM05RR, SM1RR, or SM2RR ring. Second, screw the extended external thread into a matching tube or fixed holder. Third, rotate the adjustable tube to move optics axially. Fourth, lock the final position with the supplied SM05NT, SM1NT, or SM2NT external ring. JCOPTIX offers tubes for Ø12.7 mm, Ø25.4 mm, and Ø50.8 mm optics, with maximum adjustment travels of 10.5 mm, 23 mm, or 36 mm. Custom tubes are available through technical support.
