The Integral X-Y-Z Design
Compared with other modular approaches, the RollerBlock provides a more compact stage, enabling this three axis translator to meet the performance demands of many positioning applications, over the entire 13 mm translation range. Compared to translation stages constructed from stacking single axis stages, the unibody approach, with steel construction, provides improved product lifetime within a much smaller footprint.

Compatible with the Full Line of NanoMax™ and MicroBlock™ Flexure Stages and Accessories
The movable deck has a full 13 mm of travel in three orthogonal directions and includes a grooved top plate which ensures alignment of our full line of optical accessories. The deck height of this compact stage matches the 62.5 mm deck height of our flexure based translation stages. Utilizing this standard deck height allows this longer travel stage to be incorporated into complex optical systems built around our popular flexure based stages, such as our MicroBlock and NanoMax series.

The Differential Micrometer Heads
The DRV304 Differential Micrometers used in the RBL13D utilize a unique mechanism which converts a relatively large displacement of the external knob into a relatively small displacement of the center fine-adjustment spindle. The design has the additional benefit of providing a uniformly smooth feel that is independent of load. Two large knobs are provided, one for the coarse adjustment and one for the differential adjustment, thus adding to the overall sensitivity of the unit. The coarse adjustment knob provides 13 mm of total travel with 5 µm resolution while the differential knob provides 300 µm total travel with a 0.50 µm resolution.

Interchangeable Top Plate
The Top Plate of the RBL13 stages can be replaced with the RB13P1 Adapter Plate shown above. This optional mounting plate has a generous array of 1/4"-20 (M6 x 1.0) and 8-32 (M4 x 0.7) mounting holes to adapt the RollerBlock stage to general purpose breadboard-type applications.

Custom Configurations
For applications requiring very precise control, the manual actuators can be replaced with Piezo-Assisted Differential Micrometers (DRV517). In addition to the standard micrometer adjustment described above, these drives give a piezo travel of 30 µm and a resolution of 10 nm. We can also supply the stage in left hand configurations, or without drives for fitting 3rd party actuators. For special requirements to meet the needs of your specific application please contact your nearest Thorlabs office.

A response from Tyler at Thorlabs to melsscal: The micrometers that are included with the stage are the 148-801ST. The micrometers can be swapped out with DRV504 differential drives or the DRV517 differential micrometer with piezo element. Thank you for your interest in our stage. If you have any addition questions, please post them.

Can u suggest suitable stepper motor, piezo-micrometer, differential micrometer, or standard micrometer actuators which can be used with the model RB13D/M ?

3-Axis RollerBlock with Differential Micrometers

The combination of the steel and aluminum construction of the RollerBlock™ translator is ideally suited for a broad range of photonics applications. The crossed roller bearing design provides a vertical load capacity of 9.7 lbs (4.4 kg) while maintaining the sub-micron resolution provided by the high precision actuators.

RB13P1 Top Plate Shown Replacing the MMP1 Crossed Groove Mounting Plate on a Flexure Stage
Item # RB13P1 RB13P1/M MMP1 MMP1/M
  • RB13P1 Adapter Plate for General Purpous Accessories and Components
    • Array of Thirteen 1/4"-20 (M6) and Twelve 8-32 (M4) Tapped Mounting Holes
  • MMP1 Standard 3-Axis Stage Top Plate (Included with All 3-Axis Stages)
    • Two 3 mm Wide Central Keyways for Aligning Multi-Axis Stage Accessories
    • Sixteen 6-32 (M3) Taps for Mounting Cleats
    • Four 4-40 (M2) Taps
    • Nine 8-32 (M4) Taps

The RB13P1(/M) Adapter Plate is designed as a replacement option for the standard MMP1(/M) grooved top plate sold with the stages above. Four counterbores that accept 6-32 (M3) screws allow it to be attached to the above stages. The 2.36" x 2.36" (60 mm x 60 mm) mounting surface is the same as the MMP1(/M) top plate that is included with the above stages. For complete details on the dimensions and tap locations of this top plate, please see the mechanical drawings below.

The MMP1(/M) Top Plate is included with the stages sold above but can be purchased separately as well. This plate features two 3 mm wide central keyways in a crossed pattern to allow for rapid configuration while maintaining accessory alignment, making this plate ideal for fiber launch applications. This "crossed groove" design allows for the NanoMax stages to be used in left- or right-handed configuration. The plate also contains an array of 4-40 (M2), 6-32 (M3), and 8-32 (M4) tapped mounting holes for securing and mounting various components. For complete details on the dimensions and tap locations of this plate, please see the mechanical drawings below.
