Features
Lens tubes are ideal for creating compact optical subassemblies. The Ø30 mm lens tubes sold here can be used to house one or several optical elements. Optics are separated and secured by retaining rings that are positioned at the desired depth within the lens tube using a spanner wrench. These stackable lens tubes are compatible with all SM30-threaded (M30.5 x 0.5) components. The lens tubes ship with one retaining ring; additional retaining rings can be purchased separately. In addition to the Ø30 mm lens tubes featured on this page, Thorlabs also offers Ø1/2", Ø1", Ø2", and Ø3" versions, each of which is equipped with an SM thread standard that depends on the tube diameter. Adapters for SM30-threaded components are also available on this page. These can be used to switch from the Ø30 mm standard to either our Ø1" or Ø2" standard. Via a two-step process, it is also possible to switch to our Ø1/2" or Ø3" standards. Threading specifications for Thorlabs' lens tube and cage system components can be found on the Threading Specs tab. ![]() Click to Enlarge When an engraved lens tube is attached to another lens tube, the engraving of the connected end is no longer visible. ![]() Thorlabs' Threading SpecificationsThorlabs' lens tubes utilize a series of non-standard threadings. Threading specifications are given below for our SM threadings utilized in our lens tube and cage system components so that you can machine mating components to suit your application. We also offer products with C-Mount and RMS threadings, and the specifications for these threadings are also given below. Please note that other manufacturers may have different tolerances for these threads. For other thread specifications that are not listed here, please contact Tech Support.

These stackable Ø30 mm lens tubes provide a fast and easy means for building compact optical assemblies. Their stackable design and direct interfacing with any SM30-threaded (M30.5 x 0.5) components provide flexibility for complex optomechanical assemblies. One SM30RR retaining ring is included with each lens tube. Additional retaining rings can be purchased separately. ![]()

![]() SM30RR: Retaining Rings SPW607: SM30 Spanner Wrench SPW801: Adjustable Spanner Wrench
The innovative design of the SPW801 Adjustable Spanner Wrench provides one-handed adjustment of the wrench blades, allowing for dynamic fine tuning of the blade separation to match spacing requirements exactly. The reversible blades contain an edge-offset fine point on one end and a flat blade on the opposing end (SPW102 replacement blades are available). This wrench is ideally suited for inserting the retaining rings into our Ø1/2", Ø1", Ø30 mm, Ø2", and Ø3" lens tubes. Please note that the SPW801 wrench can withstand a maximum torque of 80 in-lbs. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
