Operation principle and modules工作原理及组件

Principle of operation工作原理

Laser light of 1064nm is emitted from a fiber laser, then focused on a target surface through the glavo scanner and f-θ lens, The laser marker works by moving the focal point on the X-Axis, Y-axis  with galvo scanner, there will be laser mark on workpiece because laser can ablate materials ,and we can adjust laser focal point position for different parts.

光纤激光器产生1064nm的激光，投射到高速扫描振镜的反射镜片,再由计算机控制振镜快速转动，使激光在X、Y方向扫描，通过场镜聚焦在加工工件上。使加工工件表面烧蚀，在工件表面形成各种标记。针对不同工件需求我们可以手动调节Z轴升降优化焦点位置。

Galvo scanner and focal system振镜聚焦系统

Galvo scanner is perfectly tailored for typical laser marking applications. The scan head achieves 800 characters per second with good marking quality, thus setting new standards in its class. 10mm aperture is ideal for use with typical fiber lasers. And the housing's minimal volume facilitates integration into even the tightest spaces. This galvo scanner is available for 1064nm laser wavelength and combinable with a number of objectives. Schematic diagram as follows.

采用为激光打标量身定制的高速扫描系统，可以实现每秒800字符的高质量打标，是该级别中的佼佼者。拥有10m的入光口径非常适合光纤激光器，结构紧凑，可以和多种场镜组合使用。

Laser focus adjustment system焦点调节系统

The FTR-200I laser marking machine is equipped with Z axis for laser focal point adjustment. The optimum focal point position for the laser is set manually, it is better for marking application when laser focus is located at workpiece surface.

FTR-200I晶圆打标机拥有一个Z轴焦点调节系统，我们通过一个Z轴升降来进行焦点位置的调节，当加工件表面处于激光焦点上时，加工出来的产品质量较好。
