DMH06 Series Adjustment Screws
Description: DMH06 is based on ACFS and NAFS series thread, we have improved the manufacturing process step by step and developed a differential thread with a theoretical resolution of 0.001mm, which improved the sensitivity and convenience for precision adjus

Application context
Application guidance is derived from the product family and tied to the model-specific selection fields above.
Fine-pitch screws convert a comfortable knob rotation into a few microns of travel.
Raise the resolution of a mount already in service by changing only its adjusters.
Radial locking holds the setting once alignment is complete, through handling and thermal cycling.
System integration
Use these checks to connect DMH06 to the surrounding optical, mechanical and control system. Every value shown is taken from this model's own specification record.
Technical FAQ
Mounting Hole Size(mm): Ø12×10. Match the thread standard and hole pitch before ordering. Metric and imperial hardware interchange only through an adapter, and a thread that is nominally similar is not necessarily the same pitch.
Coarse adjustment range(mm): 13 · Fine adjustment range(mm): 0.5. 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.
Net weight(g): 36. 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.
Before you specify
Engineering context for choosing this class of component, with the tradeoffs worked through on real specifications.
Opto-mechanicsVibration, thermal drift and mechanical integration are one problem. Budget the motion at the sample, then specify the table, the isolation, the mounts and the beam height that budget asks for.
