LBTEK-Your Trusted Partner For Optoelectronic Experiments!

Product Description

Suitable for building compact optical systems
SM05 threaded standard
Available in three configurations: internal-external threads (SM05-xxA), internal threads (SM05-xxB), and external threads (SM05-xxC)
Light-blocking design, accommodates Ø12.7 mm optical elements

The SM05 lens tube from LBTEK is commonly used to secure optical components with a diameter of Ø12.7 mm or to block stray light in optical paths, preventing environmental light from affecting the system. LBTEK's SM05 lens tubes are available in three versions: with both internal and external threads (SM05-xxA), internal threads only (SM05-xxB), and external threads only (SM05-xxC). The lens tubes can be combined to extend their length, facilitating the rapid assembly 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 SM05 lens tubes, LBTEK also offers SM1 and SM2 lens tubes, along with compatible accessories such as lens tube adapters, retaining rings, and retaining ring wrenches.
