Application context
Why this design is used
Application guidance is derived from the product family and tied to the model-specific selection fields above.
Preparing a reference wavefront
Produce the smooth wavefront interferometry and holography need at the input.
Beam expansion with filtering
Combine pinhole filtering and collimation in one assembly ahead of the experiment.
System integration
Integration and compatibility
Use these checks to connect APAS80-1A to the surrounding optical, mechanical and control system. Every value shown is taken from this model's own specification record.
- Mounting interface
- Mounting Hole: 2XM4
- 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
- Adjustable Range(mm): 0~13
- 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): 215
- 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.
