Application context
Why this design is used
Application guidance is derived from the product family and tied to the model-specific selection fields above.
Constrained mounting positions
Reach optics in places where a standard post and holder will not physically fit.
Application-specific fixturing
Purpose-built retention for a component whose handling requirements are unusual.
System integration
Integration and compatibility
Use these checks to connect NMDM250 to the surrounding optical, mechanical and control system. Every value shown is taken from this model's own specification record.
- Optic it accepts
- Optic Size(mm): Ø250 · Optic Edge Thickness(mm): ≤30
- Check diameter and thickness together. A holder that accepts the diameter can still fail to retain an optic that is thinner than its minimum, and clear aperture is normally smaller than the optic the mount holds.
- Mounting interface
- Mounting Hole: Ø6.6 counter bore
- 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.
- Adjustment
- Resolution: angular adjustment per revolution(°): ≈0.105
- 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.
- Dimensions and mass
- Net Weight(Kg): 7.6
- 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.
Technical FAQ
Integration questions for NMDM250
Which optics fit the NMDM250?
Optic Size(mm): Ø250 · Optic Edge Thickness(mm): ≤30. Check diameter and thickness together. A holder that accepts the diameter can still fail to retain an optic that is thinner than its minimum, and clear aperture is normally smaller than the optic the mount holds.
How does the NMDM250 mount?
Mounting Hole: Ø6.6 counter bore. 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.
What adjustment range does the NMDM250 offer?
Resolution: angular adjustment per revolution(°): ≈0.105. 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.
What are the dimensions of the NMDM250?
Net Weight(Kg): 7.6. 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.
