Ftanθ。它是经过特别设计使得光束入射角与像面上的光斑位置满足线性关系，从而可以通过控制入射光束的扫描角来控制光斑在像面上的位置，形成线性的扫描速率，最终<a href="http://laser.oecr.com" target="_blank" class="relatedlink">激光</a>束能够在整个打标平面内形成均匀大小的聚焦光斑。 <br /> 扫描透镜应用范围：激光打标、雕刻、快速成型、钻孔、切割、焊接等系统中。 <br /> 扫描透镜工作波长：10.6um、1064nm、532nm、355nm、266nm。<br /> <br /> <div align="left">一Co2激光场镜。</div><div
