Optical Rails

Thorlabs offers five different sizes of optical rails for constructing 1D, 2D, or 3D optomechanical assemblies. The rails are machined from extruded aluminum for superior parallelism and rigidity. These rails are well suited for building long, parallel beam paths; optical enclosures; or large-scale, load-bearing structures. Size adapters permit parts from our 34 mm, 66 mm, and 95 mm options to be combined into one setup.
