这似乎是一个枪瞄光学系统，物镜有点特别。传函还好，畸变较大，不过你没有写上技术参数，也不知产品目的，无法说。

<P>场镜的作用没有达到。</P><P>质量很差</P>

<P>倍率2.4，视场10度，产品是一个枪瞄，不知道如何评价，不知道成像很差，差在哪里？</P>

<P>没办法自己re啊，冰天雪地跪求高人指点啊。</P>

gqhua 发表于 2004-11-20 17:49:00

<P>视场10度,物镜口径15MM,系统细长,其渐晕系数可能很小,观察时亮度太低.</P>

出瞳直径不足1mm是不行的

walk5000 发表于 2004-11-20 21:46:00

<P>谢谢大家热烈评论，</P>
<P>我想告诉大家的是，出瞳直径6.6,出瞳距离40，场镜之所以没有选择大的光焦度是因为要保证出瞳距离，渐晕小于50%，不知道RMS如何。我已经不能在调小了。</P>
