Application context
Why this design is used
Application guidance is derived from the product family and tied to the model-specific selection fields above.
Cylindrical optic clocking
Set the rotational orientation of a cylindrical lens so its power axis lands where intended.
Beam-folding geometry
Hold a folding prism steady where a mirror pair would introduce extra alignment freedom.
System integration
Integration and compatibility
Use these checks to connect PHLM-3 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): φ25~φ45
- 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: Sink holeφ11
- 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
- Adjustment Angle Range (°): ±3 · Tilt Resolution: angular adjustment per revolution(°): ≈0.23
- 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 Treatment: Aluminium alloy, surface treated by black anodic oxidation.
- 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): 650
- 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 PHLM-3
Which optics fit the PHLM-3?
Optic Size (mm): φ25~φ45. 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 PHLM-3 mount?
Mounting Hole: Sink holeφ11. 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 PHLM-3 offer?
Adjustment Angle Range (°): ±3 · Tilt Resolution: angular adjustment per revolution(°): ≈0.23. 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 PHLM-3 made from?
Main Body Material and Treatment: Aluminium alloy, surface treated by black anodic oxidation.. 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 PHLM-3?
Net Weight (g): 650. 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.
