Application context
Why this design is used
Application guidance is derived from the product family and tied to the model-specific selection fields above.
Cavity and interferometer alignment
Hold pointing where a few microradians of drift is visible directly in the measurement.
Repeatable optic exchange
Kinematic seating returns an optic to the same orientation after it has been removed.
System integration
Integration and compatibility
Use these checks to connect NMGC50.8 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): φ50/φ50.8 · Optic Edge Thickness (mm): 3~5
- 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: M6,φ8 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
- Travel range(Z axis)(mm): MAX6 · Resolution: angular adjustment per revolution(°): ≈0.29
- 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
- Main Body Material and Surface Treatment: Black anodized aluminium alloy
- 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
- Net Weight(g): 150
- 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 NMGC50.8
Which optics fit the NMGC50.8?
Optic Size(mm): φ50/φ50.8 · Optic Edge Thickness (mm): 3~5. 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 NMGC50.8 mount?
Mounting Hole: M6,φ8 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 NMGC50.8 offer?
Travel range(Z axis)(mm): MAX6 · Resolution: angular adjustment per revolution(°): ≈0.29. 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 is the NMGC50.8 made from?
Main Body Material and Surface Treatment: Black anodized aluminium alloy. 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.
What are the dimensions of the NMGC50.8?
Net Weight(g): 150. 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.
