Features

  • Easily Construct Multi-Element Optical Systems
  • Wide Range of SM05-Compatible Options Available
  • Directly Accepts Ø1/2" (Ø12.7 mm) Optics
  • Compatible with Our 16 mm Cage Systems
  • Available With or Without External SM05 Threads
  • Vacuum-Compatible Options Available
  • Can be Used with Ø5 - Ø9 mm Optics by Purchasing a Small Optic Adapter

Lens tubes are ideal for creating compact optical subassemblies. The Ø1/2" lens tubes sold here can be used to house one or several optical elements, as shown in the diagram of a beam expander below. Optics are separated and secured by retaining rings that are positioned at the desired depth within the lens tube using our SPW603 or SPW603L spanner wrenches. Depending on the item purchased, one or two retaining rings are included (see below for details). Additional retaining rings can be purchased separately. In addition to the Ø1/2" lens tubes featured on this page, Thorlabs also offers Ø1", Ø30 mm, Ø1.5", Ø2", and Ø3" versions, each of which is equipped with an SM series thread standard that depends on the tube diameter. Vacuum-compatible versions of our Ø1/2" and Ø1" stackable lens tubes are available from stock; customers can request vacuum-compatible lens tubes at other lengths and diameters by contacting Tech Support.

Thorlabs' Threading Specifications

Thorlabs' 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.

Hi guys: It is desirable to see in the ThorLabs Catalogue Ø1/2" lens tubes without external SM05 threads, but with the optic retention lips, similar to the Ø1" lens tubes SM1L10E or SM1L05E. Best wishes. Dr. P.A.Vokhmin
YLohia  (posted 2020-05-01 03:19:38.0)
Hello Peter, thank you for your suggestion. I have posted your request to our internal engineering forum for further consideration as a future product.
swaush  (posted 2017-04-27 17:22:53.673)
Hello Could you let us know the manufacturing tolerance of the lens tubes without external threads, 1.5 and 2 inch length? We would need the tolerance of the length and outer diameter.
nbayconich  (posted 2017-04-28 11:06:16.0)
Thank you for contacting Thorlabs. A Techsupport representative will contact you directly regarding our mechanical tolerances.

Hello,this is Wei Qi,from Kagawa Unv. Japan. We want to buy SM05L05,but we don't know that the lens(Diameter:12.7mm or smaller)can be used in the lens tubes? If the lens(Diameter:12.7mm or smaller)can be used in this lens tubes, the other parts is necessary? You can contact me by e-mail s13d504@stmail.eng.kagawa-u.ac.jp Thank you very much. Regards,
tcohen  (posted 2013-05-30 12:39:00.0)
Response from Tim at Thorlabs to Wei: The retention lip is .450” and lenses with a diameter larger than that will be restricted. A 12.7mm lens will pass through the SM05 threads to the retention lip and be held in with a retaining ring (included). Smaller optics can be adapted to the SM05 standard with adapters such as our LMRA series: http://www.thorlabs.com/NewGroupPage9.cfm?ObjectGroup_ID=59.
jlow  (posted 2012-07-31 12:19:00.0)
A response from Jeremy at Thorlabs. Thank you for your feedback. I have forwarded your feedback to our engineering group to be added. The inner diameter for the part you referenced is Ø0.450".
user  (posted 2012-07-31 09:36:49.0)
The dimension of the ID of the externally threaded end is missing from the SM05L05 lens tube drawing. As this diameter defines the maximum aperture of the back end of the lens tube i would consdier it an important number to provide. Please be kind enough to add this dimension.
jjurado  (posted 2011-02-15 08:39:00.0)
Response from Javier at Thorlabs to sivan.jonathan: Thank you very much for submitting your request. I will send you the specs for our SM05 threads to your e-mail. We will also post this information on the web shortly.

Hello, I need to interface with this product, both to external and internal threading. Can I recieve the engineering specs for these threads (they are not standard). Specifically tap, diameters etc...

Vents along the threading and at the ends of these tubes provide a free path for air to escape when under vacuum.
  • Stackable Design Enables Multi-Element Optical Systems
  • SM05-Threaded (0.535"-40) Bore Directly Accepts Ø1/2" (12.7 mm) Optics
  • Compatible with SM05-Threaded Vacuum Components

These stackable Ø1/2" lens tubes provide a fast and easy means for building compact optical assemblies. Their stackable design and direct interfacing with any SM05-threaded (0.535"-40) components provide flexibility for complex optomechanical assemblies. Made from 6061-T6 aluminum, these lens tubes are vacuum compatible down to 10-6 Torr. One vacuum-compatible SM05-threaded retaining ring is included with each lens tube. Please contact Tech Support for replacements.

These vacuum-compatible lens tubes feature venting channels along the internal threading and at the ends of each tube. These channels allow air trapped between mounted optics an easy means of escape during pumpdown.

Ø1/2" Lens Tubes Without External Threads

  • SM05-Threaded (0.535"-40) Bore Directly Accepts Ø1/2" (12.7 mm) Optics
  • Accommodates Ø5 - Ø9 mm Optics by Purchasing a Small Optic Adapter
  • Unlike Stackable Lens Tubes, Optics can be Accessed from Both Ends
  • Use Lens Tube Couplers to Stack Multiple Lens Tubes
  • Allows Coupling of Two Externally SM05-Threaded Components

Unlike our Ø1/2" stackable lens tubes featured above, these internally threaded lens tubes do not feature a lip at one end nor do they have external SM05 threading. Therefore, optics housed inside can be accessed from both ends. To join these lens tubes end-to-end, use an SM05T2 Lens Tube Coupler. Two SM05RR Retaining Rings are included with each lens tube.

Ø1/2" Slotted Lens Tubes

Slotted Lens Tube
Click to Enlarge
The dust cover can be opened or closed by rotating it in either direction.
  • Easy Access to Optics
  • Rotatable Slip Shield Protects Optics
  • Compatible with SM05 (0.535"-40) Threaded Components
  • Available in 2" (50.8 mm) and 3" (76.2 mm) Thread Depths

These stackable Ø1/2" lens tubes with side slots provide a fast and easy means for building complex optical assemblies and adjusting the optics without disassembling the setup. Optics can be inserted into the tube and locked into position using the included SM05RR retaining rings. Simply thread the first retaining ring to the desired depth, add the optic, and then use a second retaining ring to secure the optic. Optics can be manually adjusted via the side slots without the use of a spanner wrench. The rotatable slip shield included with the lens tube has an inner diameter of 0.71" (17.9 mm) and fits over the lens tube slots to prevent unwanted light from entering the system and to keep the optical setup free from debris.

The SM05RR is our standard anodized aluminum retaining ring that ships with our Ø1/2" lens tubes as well as many other Thorlabs components and is available individually and in packs of 10. We offer six different SM05-threaded (0.535"-40) retaining rings, shown in the table to the right, which have unique features and can replace an SM05RR retaining ring. Please keep in mind that due to the increased thickness of some retaining rings, the maximum optic thickness that can be housed inside our standard SM05-compatible mounts will be diminished in some cases.

Spanner Wrenches
We offer three spanner wrench choices that can be used with these retaining rings. The SPW603 and SPW603L Spanner Wrenches have a hollow design that enables retaining rings for our SM05 series of lens tubes to be adjusted and installed without obscuring the beam path. For use with longer lens tubes, multiple SPW603 spanning wrenches can be stacked to extend the wrench's maximum reach. Alternatively, the SPW801 Adjustable Spanner Wrench can also be used to position SM05-threaded retaining rings. Please note that the SPW801 wrench can withstand a maximum torque of 80 inch-pounds. We also offer the SPB05 Spanner Bit, which can be used with a standard 1/4" hex driver (sold separately). The SPB05 is included as part of the SPB600 Spanner Wrench Bit Kit.
