With a 25 mm x 25 mm profile, Thorlabs' XE25 Construction Rails are our most compact and lightweight option for building three-dimensional mechanical structures. They consist of extruded lengths of aluminum that feature channels on all four sides, as shown in the image at the top of the page. These channels make the rails mechanically compatible with other optomechanical components. For instance, by inserting T-Nuts into the channels, any 8-32 (M4) or 1/4"-20 (M6) optomechanical component can be fastened to the rail sides. The channels are also perfectly sized to hold enclosure panels made of black hardboard or plexiglass, as is done with our optical enclosures.

Our 25 mm rails are offered in pre-cut lengths from 9" to 48" (225 to 1200 mm) and are finished with a durable, black anodized coating. The centered 1/4"-20 (M6) tapped hole on both ends allows the rail to be mounted directly to a breadboard or optical table. Upon request, we can provide these anodized rails in custom lengths from 2.5" to 79" (50 to 2000 mm), or we can provide the raw rail extrusion in lengths up to 3 m (9.8').

Thorlabs' accessories for assemblies made of 25 mm rails include corner cubes and brackets, T-Nuts, low-profile channel screws, breadboard mounting accessories, and rail joiners. In addition, we offer optical enclosures, enclosure accessories, and "do-it-yourself" tools like taps, tap guides, and drill guides for home-built XE25-based constructions.
