Glossary Of Laser Engraving and Cut Terms

Depth of Field Depth of field in laser engraving describes the range of distances over which the engraved image remains in acceptable focus, from the nearest to the farthest point on the material's surface. It is determined by the depth of focus and the numerical aperture of the laser optics. Engravers consider the depth of field when selecting engraving parameters to ensure that the entire design remains sharply defined, even on materials with uneven surfaces or varying thicknesses. Considering the depth of field enables engravers to select appropriate focal settings and laser parameters, ensuring that the entire engraved surface remains sharp and well-defined, regardless of its topography or irregularities. |
