Product description

PLH3D Height Reference Tool (HRT) is used to initially set a PLH3D-Series laser head at its nominal working distance. Depending on the laser model, the HRT can be used to set a distance of 60, 35 or 21 mm (2.362, 1.377 or 0.827 inches) from the working plane.

How to use Height Reference Tool:

  • Mount the laser head on your CNC machine.
  • Place the HRT on the processed material and lower the laser head until it is positioned slightly above the upper surface of the HRT.
  • When in close proximity to the HRT, decrease the laser by 0.5mm to ensure careful adjustment and prevent any risk of crushing the HRT and material.
  • Mount the laser head on your CNC machine.


What is the difference between a shorter and a longer working distance?

  • A shorter working distance for a given lens results in a smaller beam spot size (tighter focus) and thus higher power density. It is often used for higher resolution engraving, higher speed engraving, cutting materials that are either, or any time a higher power density is preferred. However, the beam will also converge and diverge faster for a closer focus, so it is not always recommended for cutting all materials.
  • A longer working distance produces a larger beam spot and thus lower power density. It is usually preferred for engraving a wider line, cutting a thicker material due to the reduced convergence and divergence, or when a long distance between the laser head and the plane of the object to be engraved is necessary. For setting the working distance of the frequently chosen High-Resolution Mounted Triplet Lens for PLH3D-Series, we recommend the PLH3D-Series Focus Adjuster accessory.
