Focus Lens The focus lens in laser engraving systems is an optical component responsible for converging the laser beam to a precise focal point on the material surface. The focus lens helps ensure that the laser energy is concentrated at the desired location, enabling fine control over engraving depth and resolution. Choosing the appropriate focus lens is essential for optimizing engraving performance, as different lens types and focal lengths cater to specific engraving requirements, such as engraving depth, spot size, and material compatibility. |
