Adjustable Lens Tube

LBTEK adjustable lens tubes allow for the adjustment of optical components' positions within an optical system. These tubes can also be combined with corresponding SM05, SM1, and SM2 threaded lens tubes for fine-tuning. During position adjustment, rotate the optical component back and forth along the optical axis until the desired position is reached, then secure it with an external retaining ring. Currently, the internal thread depth of all adjustable lens tubes is 12.5 mm. Additionally, adjustable lens tubes can be integrated into coaxial systems by pairing them with coaxial mounting plates or coaxial system rotary mounts. For free-space applications, they can also be installed using fixed tube mounts. Besides standard SM05, SM1, and SM2 lens tubes, LBTEK also provides compatible lens tube adapters, retaining rings, and retaining ring wrenches as accessories.
