Set-and-forget alignment
Adjust once during setup and lock, on axes that do not need to move again during the run.

Application context
Why this design is used
Application guidance is derived from the product family and tied to the model-specific selection fields above.
Coarse positioning ahead of fine stages
Establish the optical axis by hand before a piezo or motorised stage takes the fine motion.
Prototyping and teaching rigs
Reconfigure a layout quickly, with no cabling, controllers or electrical noise added to the experiment.
System integration
Integration and compatibility
Use these checks to connect MJ120 to the surrounding optical, mechanical and control system. Every value shown is taken from this model's own specification record.
- Adjustment
- Travel range(mm): 120
- Adjuster pitch sets the sensitivity you can actually work at. Confirm whether the stated figure is a total range or a per-revolution increment, and whether the mechanism is locked after adjustment.
- Material and finish
- Stage surface height range(mm): 110~230 · Stage surface size(mm): 250×150
- Aluminium moves about 23 ppm per kelvin and stainless about 16. In a path where thermal drift is already budgeted, the material of the mount belongs in that budget rather than in the appearance of the part.
- Dimensions and mass
- Load capacity(Kg): 30 · Weight(Kg): 4.5
- Use the stated geometry and mass to fix beam height, clearance and the load carried by whatever this part is bolted to. These are the numbers that decide whether adjacent components physically collide.
