Features
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.

The XT34A66 Double Dovetail Adapter Clamp makes 34 mm rails mechanically compatible with 66 mm rails, facilitating the design of complex optical instruments. Like all our rail clamps, it can be slid along the rail assembly for coarse positioning prior to being locked down. ![]() 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. ![]() 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. | |||||||||||||||||
