Collimator Mounting Adapters

Hide Overview

OVERVIEW

Features

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 or RMS threading as well as adapters that have 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 non-kinematic 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. Smooth bore and SM1-threaded (1.035"-40) kinematic adapters with pitch and yaw adjustment are also available below for Ø11 mm or Ø12 mm cylindrical components.

  • Nylon-Tipped Setscrew Secures GRIN Collimator

These adapters are designed to mount Thorlabs' GRIN Lens Fiber Collimators in SM05-compatible mounts, lens tubes, and cage components. A 1/16" (1.5 mm) 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 lens tube. A version of this mount with SM1-threadeing is available, please see the SM1PT below.

F671SMA-405 SMA Fiber Collimator with an MHP200L02 Patch Cable Secured in an AD11NT Adapter
  • Smooth 1" (25.4 mm) Outer Diameter
  • Two Setscrews Secure Collimator in Adapter
  • Versions for Fixed Collimators, Collimation Tubes, and Other Cylindrical Components

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" (1.5 mm) 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.

TC06FC-543 Triplet Collimator Held in a KAD12NT Adapter and Mounted into an FMP1 Fixed Optical Mount
  • Compatible with Ø11 mm or Ø12 mm Cylindrical Components
  • Pitch/Yaw Adjustment: ±6° (KAD11NT) or ±5° (KAD12NT)
  • Resolution of ~24 mrad/rev
  • Smooth 1" Outer Diameter

These unthreaded, Ø1" kinematic adapters are designed to provide pitch/yaw adjustments of ±6° or ±5° for Ø11 mm or Ø12 mm cylindrical components, respectively. They can be used to adapt many of our fixed fiber collimators, laser diode modules, triplet collimators, and other components to our selection of smooth bore mounts for Ø1" optics, such as the FMP1 fixed optic mount.

Two 80 TPI fine adjustment screws on the front plate of the adapter control the pitch and yaw position and can be turned using a 5/64" (2.0 mm) hex key. The front plate of the adapter also features engraved axes that are aligned with the pitch and yaw axes, and two holes for use with our SPW801 spanner wrench. Mounted components are held by a brass locking screw, which also requires a 5/64" (2.0 mm) hex key. Please use care when mounting components in these adapters, as over tightening of the setscrew can cause damage to the mounted component.

F240SMA-A Fiber Collimator with an MHP200L02 Patch Cable Secured in the AD12F Collimator Adapter
  • External SM1 (1.035"-40) Threads
  • Setscrews Secure Collimator in Adapter
  • Versions for Fixed Collimators, Collimated Laser Diodes, and Collimation Tubes

These SM1-threaded (1.035"-40) collimator adapters are designed to mount Ø3.5 to Ø16 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. Inline 1/16" (1.5 mm) 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. Each adapter includes two of these setscrews, except for SM1PT and AD9.5F, each of which have one setscrew.

Except for the AD8F and AD15F, each of these adapters contains holes on opposing sides of the central hole that are mechanically compatible with our SPW909 and SPW801 spanner wrenches.

  • Kinematic Adapters for Ø11 mm or Ø12 mm Cylindrical Components
  • Pitch/Yaw Adjustment: ±6° (KAD11F) or ±5° (KAD12FF)
  • Resolution of ~24 mrad/rev
  • Externally SM1-Threaded (1.035"-40)

These externally SM1-threaded (1.035"-40) kinematic adapters are designed to provide pitch/yaw adjustments of ±6° or ±5° for Ø11 mm or Ø12 mm cylindrical components, respectively. This adjustment range can be restricted by the available space inside a SM1-threaded lens tube when used with a long component. Compatible components include many of our fixed collimators, laser diode modules, and triplet collimators.

This adapter is particularly useful when combined with our Ø1" lens tubes30 mm cage plates, or LM1XY translation mount. A Ø1.25" SM1NT locking ring is included with the KAD11F and KAD12F to ensure stable mounting. To mount the adapter inside a lens tube or other component, first thread it into the desired position and axis orientation, and then tighten the locking ring against the end of the lens tube or mount.

Two 80 TPI fine adjustment screws on the front plate of the adapter control the pitch and yaw position and can be turned using a 5/64" (2.0 mm) hex key. The front plate of the adapter also features engraved axes that are aligned with the pitch and yaw axes, and two holes for use with our SPW801 spanner wrench. Mounted components are held by a brass locking screw, which also requires a 5/64" (2.0 mm) hex key. Please use care when mounting components in these adapters, as over tightening of the setscrew can cause damage.
