4-Axis MicroBlock Stages, 62.5 mm Deck Height
Low-Profile Device Stage
±5° Pitch and Yaw Rotation
Thin-Profile Device Stage
6 mm of Vertical Translation
13 mm of Horizontal Translation
Thorlabs' 4-Axis MicroBlock™ Stages are designed for precise orientation of photonics components with respect to one of our high-performance multi-axis stages. When combined with any of our 3-axis stages (MicroBlock , NanoMax™ , or RollerBlock™), these 4-axis stages are ideal for high-performance fiber launch or single mode waveguide coupling applications that require micron resolution. They provide the four adjustments, two translation and two rotation, required to align two optic axes. These four independent degrees of freedom provide 13 mm of horizontal translation, 6 mm of vertical translation, and 10° of pitch and yaw adjustment. The longer range of the fine, ball bearing horizontal adjustment allows for motion across the full width of a waveguide device. The vertical and rotational adjustments are based on a flexure design for precise, smooth, continuous motion with negligible friction and no backlash.

For direct compatibility with our 3-axis families of stages, the 4-axis MicroBlock stages have a 62.5 mm deck height. When used with a 3-axis stage for a coupling application, these 4-axis stages are recommended for the static positioning of an optical element or device; any optimization of the coupling efficiency should be accomplished by using the 3-axis system to position the input/output device. An example of this type of system can be seen in the image to the right. For compatibility with our 6-Axis NanoMax Stages, the AMA554 Height Adapter can be used to raise the deck height of the 4-axis stages to 112.5 mm.
The thin-profile MBT401D(/M) MicroBlock Stage is recommended for applications in which space is at a premium. The narrow 3.58" (91.0 mm) width of this stage makes it ideal for use between two closely spaced coupling stages. In addition, the platform on this stage pivots about a point on the optical axis, which is at a height of 75 mm. In contrast, the low-profile MBT402D(/M) MicroBlock Stage has a shorter 3.73" (94.7 mm) overall height while maintaining the same 62.5 mm deck height. The moving platform on this stage offers fourteen 6-32 (M3 x 0.5) tapped holes for mounting multi-axis stage accessories, but it does not pivot about any point on the system's optical axis. This stage is accessible from three of the four sides, maximizing the free space available for additional equipment that your system may require.

This MicroBlock stage provides four degrees of freedom: two translation and two rotation. The 62.5 mm deck height is compatible with our 3-axis MicroBlock, NanoMax, and RollerBlock stages. We recommend this narrow stage for applications that require a device to be positioned between two closely spaced coupling stages. An extensive selection of accessories is available to mount items such as microscope objectives, collimation packages, waveguides, and fiber.

This Additional Translation Axis Stage for 4-Axis MicroBlock Stages adds a third translational adjustment to our MBT401D(/M) or MBT402D(/M) stage, allowing for the precise positioning of components along the system's optical axis. The addition of the fifth axis increases the deck height of the stage to 112.5 mm, providing compatibility with our 6-axis NanoMax stages, and increases the overall width of the stage to 5.72" (145.3 mm).
