Glossary Of Laser Engraving and Cut Terms
[1] |
Focal Length Focal length in laser engraving refers to the distance between the focal point of the laser lens and the surface of the material being engraved. It determines the spot size and focus of the laser beam on the material, affecting engraving depth and resolution. Engravers adjust the focal length to achieve optimal focus for precise and clear engraving results, especially when working with materials of varying thicknesses or contours. Selecting the correct focal length is crucial for achieving sharp and precise engraving results, as it directly affects the size of the laser spot and the depth of focus on the material surface. |
