Features

  • Integrate Collimators into Components such as Lens Tubes and Cage Systems
  • SM05-, SM1-, and RMS-Threaded Adapters Available
  • Ø1" (Ø25.4 mm) Unthreaded Adapters
  • Versions for Fixed Collimators, Adjustable Collimators, Collimation Tubes, and GRIN Lenses
  • Collimators can be Secured by Nylon-Tipped Setscrews or Directly Threaded into Adapters

These collimator adapters are designed to facilitate the integration of fiber optics into free space optical setups (or vice versa) . We offer adapters that feature external SM and RMS threading as well as adapters with a smooth 1" outer diameter. The threaded adapters are compatible with our lens tube systems, cage systems, and numerous components in our product line. The unthreaded adapters are best suited for use in kinematic mirror mounts, allowing a collimated beam to be steered by the mount. Each adapter is designed so that the optical axis of the collimator will be centered with respect to the outer diameter of the adapter.

The application photographs shown above demonstrate how these adapters are used to mount collimators within a cage system or mount. The photo above on the left shows how an AD12F adapter can be used to mount an F240SMA-A collimator and attached fiber inside a 30 mm cage system, while the photo above on the right shows how to mount a F671SMA-405 fiber collimator within a KM100 kinematic mirror mount. Detailed descriptions can be found in the caption of each enlarged photograph.

 


Ø1" Unthreaded Fiber Collimator Adapters

 

  • Smooth 1" (25.4 mm) Outer Diameter
  • Two Setscrews Secure Collimator in Adapter
  • Versions for Fixed Collimators and Collimation Tubes
Item #Intended for Use With
AD11NT FC/PC, FC/APC, or SMA Fixed Collimators (F220, F230, F260, F280 and F671) and Laser Diode Modules
AD12NT F240 Collimators (FC/PC, FC/APC, or SMA), TC12 and TC18 Collimators (FC/PC and FC/APC)
AD15NT F810 Collimators, LT Collimation Tubes, TC18 Collimators (FC/PC and FC/APC)

These collimator adapters are designed to mount fixed collimation packages in Ø1" (Ø25.4 mm) mounts. Each adapter has a double bored center hole and an unthreaded 1" (25.4 mm) outer diameter. Two nylon-tipped setscrews hold the collimation package against two lines of contact created by the double bore. Both setscrews feature a 1/16" hex socket. The adapter design centers the collimator within the outer diameter, which in turn aligns the collimated beam to the center of the mount it is held in.

 

Fixed Fiber Collimator and Collimated Laser Diode Module Adapters, SM1 Threaded

 

  • External SM1 (1.035"-40) Threads
  • Two Setscrews Secure Collimator in Adapter
  • Versions for Fixed Collimators, Collimated Laser Diodes, and Collimation Tubes
Item #Intended for Use With
AD8F Laser Diode Modules
AD11F FC/PC, FC/APC, or SMA Fixed Collimators (F220, F230, F260, F280 and F671) and Laser Diode Modules
AD12F F240 Collimators (FC/PC, FC/APC, or SMA), TC12 and TC18 Collimtators (FC/PC or FC/APC)
AD15F F810 Collimators, LT Collimation Tubes, TC18 Collimtators (FC/PC or FC/APC)
 

The AD8F, AD11F, AD12F, and AD15F collimator adapters are designed to mount Ø8, Ø11, Ø12, and Ø15 mm collimation packages, respectively, in SM1-compatible mounts, lens tubes, and cage components. The adapter has external SM1 threads and a double bored center hole. Two inline 1/16" hex setscrews with nylon tips are used to press the collimation package against the two lines of contact created by the double bore (see the mechanical drawing to the left) and position the collimation package so that its optical axis is coincident with the center of the SM1-compatible component that the adapter is placed in.

The AD11F and AD12F contain through holes on opposing sides of the central hole that are mechanically compatible with our SPW909 and SPW801 spanner wrenches.

 

Adjustable Fiber Collimator Adapter, SM1 Threaded

 

  • External SM1 (1.035"-40) Threads
  • Compatible with our Adjustable Collimators
  • Ø1/2" Counterbore for Tightening an FC Connector onto a Collimator

The AD9.5F collimator adapter is designed to mount Ø9.5 mm collimation packages, such as our adjustable fiber collimators, in SM1-compatible mounts, lens tubes, and cage components. The adapter has external SM1 threads, a double-bored central hole, and features a Ø1/2" couterbore on the back side so that an FC connector can be threaded onto the collimator. A 1/16" hex, nylon-tipped setscrew is used to press the collimation package against the two lines of contact created by the double bore and positions the collimation package so that its optical axis is coincident with the center of the SM1-compatible component that the adapter is placed in.

The through holes on opposing sides of the central hole are mechanically compatible with our SPW909 and SPW801 spanner wrenches.

 

Fixed Collimator Adapter, SM05 Threaded

 

  • Internally M11 x 0.5 and M9 x 0.5 Threaded
  • External SM05 Threads
  • Compatible with Many Collimation Packages and Aspheric Lens Cells
Item #Intended for Use With:
AD1109F Fixed Aspheric Lens Fiber Collimators and Mounted Aspheric Lenses

The AD1109F adapter is designed to mount optical components with external M11 x 0.5 or M9 x 0.5 threading in SM05-compatible mounts, lens tubes, and cage components. Thorlabs' F220, F230, and F260 series of fixed aspheric lens fiber collimation packages have external M11 x 0.5 threading, while the A390TM, A397TM, A375TM, C110TME, C220TME, C230TM, C260TM, C280TM, C330TM, C340TM, C560TME, C570TM, C671TM, A110TM, and A220TM mounted aspheric lenses have external M9 x 0.5 threading. The AD1109F can be paired with the SM1A6 adapter that converts external SM05 threading to external SM1 threading so that the AD1109F can be used in SM1-compatible mounts, lens tubes, and cage components.

 

Adapter for M11 x 0.5 Threaded Collimators, RMS Threaded

 

  • Internally M11 x 0.5 Threaded
  • Externally RMS (0.800"-36) Threaded
  • Compatible with Our F220, F230, and F260 Collimators

The RMS11P is designed to mate M11 x 0.5 threaded collimation packages to internally RMS-threaded (0.800"-36) components. The knurled outer edge allows the adapter to be secured without a spanner wrench.

 

GRIN Collimator Adapter for Lens Tubes

 

  • Externally SM05- or SM1-Threaded Version
  • Ø0.14" (Ø3.5 mm) Center Hole
  • Nylon-Tipped Setscrew Secures GRIN Collimator

These adapters are designed to mount Thorlab's GRIN Lens Fiber Collimators in SM05- or SM1-compatible mounts, lens tubes, and cage components. A 1/16" hex, nylon-tipped setscrew is used to press the GRIN lens fiber collimator against the two lines of contact created by the double-bored mounting hole. The adapters' design ensures that the GRIN lens is aligned with the optical axis when mounted into a SM05 or SM1 lens tube.
