Lens tubes are ideal for creating compact optical subassemblies with light-tight beam paths. The Ø2" lens tubes sold here can be used to house one or several optical elements, as shown in the diagram of a beam expander below. In addition to the Ø2" lens tubes featured on this page, Thorlabs also offers Ø1/2", Ø1", Ø30 mm, Ø1.5", 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.

Optics are separated and secured by retaining rings that are positioned at the desired depth within the lens tube using our SPW604 spanner wrench. Depending on the item purchased, one or two retaining rings will be included (see below for details). Additional retaining rings can be purchased separately.

Threading Specifications

The following is a general overview of screw threading. For more details regarding specifications and dimensions, please consult the Machinery's Handbook, available for purchase at many bookstores.

Features of a Thread
A thread consists of three repeating features: a crest, flank, and root (see drawing to the right). Except in special cases, threads have symmetrical sides inclined at equal angles when a vertical line is drawn through the center of a crest or root. The distance between corresponding points on adjacent threads is known as the pitch of the thread. The flank angle is defined as the angle the flank makes with a perpendicular ray drawn from the screw axis. Unless otherwise stated, threads have a flank angle of 30°, resulting in a total angle between flanks of 60°. Each feature is shown in the diagram to the right.

The major diameter is taken from the crests of a thread while the minor diameter is taken from the roots. For most screws, crests and roots do not terminate at a sharp point, so crest and root truncation values are included in the definitions of major and minor diameter. The pitch diameter is approximately halfway between the major and minor diameters.

Thread Form
A thread form is a set of rules that define the features' scale relative to one another. Common thread forms include the Unified Screw Thread Form, used in the United States of America and measured in imperial units, and the ISO Metric Screw Thread Form, used in many parts of the world and measured with the International System of Units. There are many thread forms in the Unified screw thread standard designated by either UN, which defines a flat root contour, or UNR, which defines a round root contour. These can be further described by appending more letters. For example, an extremely fine thread with a flat root contour is designated UNEF. Those forms which are not standardized by the Unified screw thread system are designated UNS.

Thread Series
Most screws are identified by their thread series. Thread series are denoted by the major diameter and density of threads. Unified threads specify density in threads per inch, while Metric threads specify the thread pitch. For example, in the Unified nomenclature, a 1/4"-20 cap screw has a 1/4" diameter barrel and the pitch is 20 threads per inch (TPI). In metric nomenclature, an M4 x 0.7 cap screw has a 4 mm barrel and the pitch is 1 thread per 0.7 mm. The term M4 x 0.7 is often shortened to just M4.

External 3, 4, 5, 6, 7, 8, 9
  • The tolerance becomes looser as the grade increases. The underlined grades are used with normal lengths of thread engagement.

Thread Class
The tolerances and allowances on a thread series are given by a thread class. Unified thread classes are alphanumeric identifiers starting with a number from 1 through 3, where 1 is the loosest tolerance and 3 is the tightest, and either A for external threading or B for internal threading.

Metric threads have a slightly more complex tolerancing method that uses tolerancing grades, designated by a number 3 through 9; and tolerancing positions, which use letters e through h. Grades provide a measure of the tolerance itself: the smaller the number, the tighter the tolerance. Positions denote the distance of the tolerance from the pitch diameter. Uppercase positioning letters indicate internal threads while lowercase positioning letters indicate external threads.

Quoting from the Machinery's Handbook, 29th Edition, p. 1885: "To designate the tolerance class, the grade and position of the pitch diameter is shown first followed by that for the major diameter in the case of the external thread or that for the minor diameter in the case of the internal thread, thus 4g6g for an external thread and 5H6H for an internal thread. If the two grades and positions are identical, it is not necessary to repeat the symbols, thus 4g, alone, stands for 4g4g and 5H, alone, stands for 5H5H."

Thorlabs' SM Series Threads
Threading specifications for our SM threads, utilized in our lens tube and cage system components, are given below so that you can machine mating components to suit your application. Most SM series threads utilize a non-standard Unified thread form, indicated by the letters UNS, with a 30° flank angle and a thread class of 2A and 2B. The exception is our SM30 series thread, which is a Metric thread form with a 30° flank angle and a tolerance of 6H/6g. We also offer products with C-Mount and RMS threads, and the specifications for these threads are given below for reference. Please note that other manufacturers may have different tolerances for C-Mount and RMS threads. For other thread specifications that are not listed here, please contact Tech Support.

Could you offer a 2 mm version of your 2.5mm SM2RR retaining rings?
cdolbashian  (posted 2021-08-19 03:05:35.0)
Thank you for reaching out to us at Thorlabs with this request. I have contacted you directly regarding regarding the feasibility of this custom version of the SM2RR.
Ludovic A.  (posted 2021-01-22 09:51:33.083)
Could you offer a 4" and/or 5" version of your 6" SM2 thick wall Extension tube? While it's acceptable to stack shorter tubes to reach the desired length, your current offering of SM2 tubes stops at 3.5" and jumps to 6". Intermediate versions of SM2 extension tubes would be much welcome (thick walled would be best, they could also be stackable (as your SM2Lxx) or without ext. thread (SM2Exx)). My current application makes use of a large format and heavy line scan lens with a long flange focal distance and I regularly use long lengths of SM2 tubes in other applications.
YLohia  (posted 2021-01-22 01:56:03.0)
Thank you for your feedback. We will consider adding other lengths of these lens tubes to our catalog in the future. For immediate customizations, quotes can be requested by clicking the "Request Quote" button above. We will discuss this customization directly.

Are the lens tubes vacuum compatible? Could you make ones that are?
YLohia  (posted 2020-08-03 02:04:10.0)
Thank you for contacting Thorlabs. These lens tubes are anodized and, thus, not vacuum-compatible. Custom unanodized versions can be requested by emailing techsupport@thorlabs.com.

Hi Thorlabs team, I would like to know what is the tolerance on tilt of a flat surface within your SM2M10 tube by using SM2 retainer ring. Regards.
llamb  (posted 2019-06-05 08:32:19.0)
Hello, thank you for contacting Thorlabs. The exact tip/tilt of an optic will greatly depend on the optic's flatness/parallelism as well as the lens tube. I have reached out to you directly to discuss this lens tube's tolerances and your application's needs further.

Slotted Lens Tubes

  • Easy Access to Optics
  • Rotatable Slip Shield Protects Optics
  • Compatible with SM2-Threaded Components

These stackable Ø2" Lens Tubes with side slots provide a fast and easy means for building complex optical assemblies and adjusting the optics without disassembling the setup. Several optics can be inserted into a single tube using multiple SM2RR 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 fits over the lens tube slots to prevent unwanted light from entering the system and to keep the optical setup free from debris. Two retaining rings and one black plastic dust cover are included with each lens tube.

SM2 Extension Tubes

The SM2E60 6" Long Extension Tube is designed to enable longer distances between optical components in lens tube systems that utilize lenses with large focal lengths. Although the ends of these extension tubes are threaded to accept our SM2 series stackable lens tubes, they feature thicker walls than our standard lens tubes, which leads to greater rigidity.

The SM2RR is our standard anodized aluminum retaining ring that ships with our Ø2" lens tubes as well as many other Thorlabs components and is available individually and in packs of 5. We offer five different SM2-threaded (2.035"-40) retaining rings, shown in the table to the right, which have unique features and can replace an SM2RR 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 SM2-compatible mounts will be diminished in some cases.

Spanner Wrenches
We offer two spanner wrench choices that can be used with these retaining rings. The SPW604 Spanner Wrench has a hollow design that enables retaining rings for our SM2 lens tubes to be adjusted and installed without obscuring the beam path. The handle is knurled for improved grip. Alternatively, the SPW801 Adjustable Spanner Wrench can also be used to position SM2-threaded retaining rings. Please note that the SPW801 wrench can withstand a maximum torque of 80 inch-pounds. We also offer the SPB2 Spanner Bit, which can be used with a standard 1/4" hex driver (sold separately). The SPB2 is included as part of the SPB600 Spanner Wrench Bit Kit.
