MicroBlock™ 4-Axis Device Platforms, 62.5mm Deck Height

The MBT401 MicroBlock™ Device Platform provides four degrees of freedom, two translation and two rotation. The 62.5mm deck height is compatible with our 3-Axis MicroBlock™ , NanoMax™ , and RollerBlock™ families of stages. We recommend this narrow platform positioning system for applications that require a device to be positioned between two coupling stages such as the MAX600 series. The extensive selection of accessories are all compatible with the platform stages. Given the large array of possible solutions to any particular alignment challenge, Thorlabs recommends that you contact one of our regional offices for expert technical assistance in configuring a system that is ideally suited to your specific needs.

The MBT402 Low Profile MicroBlock™ Device Platform is a compact, cost-effective, four-axis positioner designed for precise orientation of photonics components and other planar devices. This device is intended to allow a complex optical element that either has multiple single mode ports, or has angled output surfaces, to be properly positioned with respect to one of our high performance stages. Please note that we only recommend this device for the static positioning of the optical element or device; any optimization of the coupling efficiency should be accomplished using the NanoMax 3-Axis System to position the input/output device.

The low profile design provides a 62.5mm deck height designed specifically to work with the MAX300, MBT and RollerBlock series stages. The four independent degrees of freedom provide 13mm of horizontal translation, 6mm of vertical translation, plus 10° of pitch and 10° of yaw. This stage, when combined with any of our three axis stages (MicroBlock™ , NanoMax™ , or RollerBlock™) is ideal for building high performance fiber launch or single mode waveguide couplers. The 13mm of horizontal travel allows the individual channels of a multichannel waveguide to be readily accessed. The use of nested flexure elements ensure smooth continuous motion over all three rotational axes of movement making this device ideally suited for high resolution optical applications. Aside from the low profile, the key feature that this particular stage offers is the easy accessibility of the moving platform. The moving platform is accessible from three of the four sides, this feature maximizes the free space available for additional equipment that your setup may require.

Response from Javier at Thorlabs to gather.malte: we would not recommend using these stages in this configuration. However, if the load is small (<0.25 Kg), the stage should work well. I will contact you directly to discuss your application.

Can these stages operated when mounted on a vertical surface? I would like to mount the base of the stage to a breadboard that is tilted by 90° with regard to the surface of the optical table. Some stages cannot be used in that orientation because the springs inside are not strong enough to lift the weight of the stage back in certain orientations. (I had this with normal linear stages before.)
