SM1 Lens Tube

LBTEK lens tubes are commonly used to secure Ø25.4 mm optical components or for light path shading to prevent ambient light from affecting the system. LBTEK's SM1 lens tubes come in three versions: with both internal and external threads (SM1-xxA, SM1-xxD), internal threads only (SM1-xxB), and external threads only (SM1-xxC). The lens tube combinations can be connected to extend the length, facilitating the rapid setup of compact optical systems. By using a retaining ring wrench, the retaining ring can be positioned at the desired location inside the lens tube to separate and secure optical components. In addition to the standard SM1 lens tubes, LBTEK also offers SM05 and SM2 lens tubes, along with compatible accessories such as lens tube adapters, retaining rings, and retaining ring wrenches.
