NanoMax Parallel Flexure Stages
The 3-Axis NanoMax™ flexure stages are ideal for fiber coupling applications. The complete fiber launch systems assembled here have been configured to meet many of the most common laboratory applications. Each launch system is fully described below. Please see the NanoMax 3-Axis Flexure Stage presentation for more specific details about the stage included in these kits.
X, Y, and Z Axes are Decoupled to Maximize Stablility During Adjustment
The patented MAX300D series stage features a parallel flexure design's which has significant advantages when it is implemented in alignment applications requiring sub-micron resolution or better. Typically with a multi-axis stacked stage, touching one of the drives that is not connected to the base of the stage will result in unwanted motion within the assembly. With each of the drives on a NanoMax series stage coupled directly to the base of the stage, these adverse effects are eliminated. The fixed differential drives offer 4 mm of coarse travel as well as 300 µm of fine travel with a resolution of 50 nm per revolution. The graduations engraved on the fine travel provide a clear reference point for applications that require absolute positioning.
When considering a fiber launch system, the use of nested flexure plates in place of more traditional linear bearings provides a number of advantages. First, nearly perfect, smooth, continuous motion is achievable with a flexure mechanism. Second, a flexure mechanism eliminates the need for lubricants within the stage structure. With traditional bearings, minor imperfections in the bearing or contaminants trapped in the lubricant create localized rough spots where the displacement resolution degrades significantly. The lack of lubricants also minimizes stage creep.
Easy Alignment of Accessories
A central keyway in the top platform allows rapid system reconfiguration while maintaining accessory alignment. A wide range of accessories is available to mount items such as microscope objectives, collimation packages, wave guides, fiber and much more.
In addition, adapter plates are available to mount the NanoMax series stages to a wide range of other Thorlabs rotation and long travel linear stages.
Combined, these features make the MAX300D series flexure stages solid platforms for alignment applications that require high stability and repeatability.

2 & 3 Dimensional Alignment Packages, Please Contact Technical Support for Details
Thorlabs is happy to discuss custom optical fiber-to-fiber and fiber-to-device alignments package. Our solutions contain all the necessary mechanical stages and components, drive electronics and control software to fully facilitate either 2- or 3-dimensional alignment scenarios. The 2D packages usually include our high performance NanoMax stage equipped with internal piezos and 2 external stepper motor actuators. For full auto alignment operation the highly functional apt NanoTrak unit is combined with the apt stepper motor driver. All packages include our full apt ActiveX software suite that is further enhanced by the apt developer support CD that is included free of charge. The latter contains complete working source code alignment routines (both 2D and 3D), written in both LabVIEW and Visual Basic. These open architecture source code offerings are not only complete alignment examples, but they also form an excellent basis for further custom software development for specific user applications. The 3D packages include a second single channel APT stepper drive for motorized axial optimization of coupled light.
