OPTOGAMA: 激光擴(kuò)束器 Compact motorized laser beam expanders MEX 緊湊型電動(dòng)激光擴(kuò)束器 MEX
MEX 系列電動(dòng)激光擴(kuò)束器用于增大激光束直徑并調(diào)節(jié)發(fā)散度。標(biāo)準(zhǔn)或定制的擴(kuò)束器采用獨(dú)特的機(jī)械閉環(huán)滑動(dòng)透鏡設(shè)計(jì)，確保高指向穩(wěn)定性和最小尺寸。這些可變放大倍率（變焦）的擴(kuò)束器和縮束器是針對所需波長設(shè)計(jì)的，而且我們每種類型的擴(kuò)束器都具有電動(dòng)發(fā)散度可調(diào)節(jié)功能。
