Features

  • Adapter Clamps Integrate 34 mm, 66 mm, and 95 mm Optical Rails
  • 34 mm to 66 mm Clamp: Side-Locked Double Dovetail Adapter
  • Two 66 mm to 95 mm Clamp Options:
    • XT95A66: Rails Fixed Relative to Each Other
    • XT95R66: Easy Rotation of Joined Rails

Thorlabs manufactures three size adapters for converting between our 34 mm, 66 mm, and 95 mm optical rail systems. To securely fasten a 34 mm rail to a 66 mm rail, we offer the XT34A66 Double Dovetail Adapter, which orients the rails in parallel. To connect a 66 mm rail to a 95 mm rail, we offer two choices. The XT95A66 Fixed Adapter Plate is designed to fix rails in parallel or at a right angle, while the XT95R66 Rotation Adapter conveniently allows orientation at any relative angle. These adapters can be coarsely positioned by sliding them along the rail assembly before locking them into place.

Thorlabs offers a wide and growing complement of rails and rail accessories. By incorporating 34 mm, 66 mm, and 95 mm rails into a single setup, these size adapters provide access to a complete family of rigid, versatile building blocks suited for virtually any optomechanical setup.

What about the external-like 66mm adapter version of the XT95A66? That way cage system adapters for 66 mm rails can be used on 95 mm rails.

While you could add our cage system adapters (RCA1 for example) to a 66 mm rail and then attach that 66 mm rail to a 95 mm rail with the XT95A66, this may likely be too tall for most setups. I will add this idea for a different 95 mm rail adapter to our internal product forum for future discussion. Thank you for your feedback!

  • Designed to Fix a 66 mm and a 95 mm Rail in Parallel or at a Right Angle

The XT95A66 Fixed Adapter consists of an XT66-compatible clamp mounted directly on an XT95-compatible adapter plate with three low-profile cap screws. The tapped hole array of the adapter plate is designed to support either a parallel or a perpendicular rail orientation. To change between rail orientations, the carriage must be disassembled.

Four M6 cap screws and two T-Nuts that span the length of the plate are included with each adapter for attachment to a 95 mm rail. Please click on the image to the right for details regarding the 95 mm rail clamping mechanism.

In order to orient two rails at an arbitrary angle, please see the XT95R66 Rotation Adapter below.

  • Easily Rotate a 66 mm Rail and a 95 mm Rail Through a Full 360°

The XT95R66 Rotation Adapter consists of a rotation disk sandwiched between an XT66-compatible clamp and an XT95-compatible adapter plate. The attached rails can be rotated with respect to one another by loosening the side-mounted XT66-compatible clamp. This convenient arrangement allows any orientation between rails and minimizes disturbances to the setup.

Four M6 cap screws and two T-Nuts that span the length of the plate are included with each adapter for attachment to an 95 mm rail. Please click on the image to the right for details regarding the XT95 rail clamping mechanism.

For a simpler clamp that orients rails either in parallel or at a right angle, please see the XT95A66 Fixed Adapter above. Our fixed adapter is 3 mm shorter than our rotation adapter, conserving space in tight situations.
