本人光信息科學(xué)與技術(shù)專(zhuān)業(yè)大四學(xué)生，沒(méi)有zemax基礎(chǔ)，最近幾天在研究zemax，畢業(yè)設(shè)計(jì)做He-Ne激光光束聚焦物鏡的設(shè)計(jì)，按老師要求用zemax仿真出一個(gè)例子，就是論壇上的“基于Zemax的He_Ne激光光束聚焦物鏡的設(shè)計(jì)”。 7HfA{.|m

中間提到像差校正時(shí)用LONA控制軸向球差，控制不住時(shí)加入SPHA，小弟在這里不懂LONA該如何操作，論壇上找的資料也沒(méi)有提到LONA，網(wǎng)上也沒(méi)有找到相關(guān)該如何操作，求大神指點(diǎn)

LONA is the measure of defocus at the wavelength defined by WAVE for this operand from the current image plane. For your case, if you are designing a laser system, though in reality has small bandwidth, is assumed to be monochromatic. So using SPHA to control the aberration shall be sufficient.
