Application context
Why this design is used
Application guidance is derived from the product family and tied to the model-specific selection fields above.
Establishing a reference axis
Targets and irises give a repeatable datum to align the rest of the path against.
Checking alignment
Verify beam height, centration and pointing without disturbing what is already set.
System integration
Integration and compatibility
Use these checks to connect NAT38.1 to the surrounding optical, mechanical and control system. Every value shown is taken from this model's own specification record.
- Material and finish
- Main Body Material and 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): 14.5
- 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.
