alt="" />><FONT color=#000000> 你好！你提的问题答复如下：</FONT></P><br /> <<img src="static/image/smiley/default/titter.gif" smilieid="9" border="0" alt="" />><FONT color=#000000>1 入瞳的大小和位置是否是不变的</FONT></P><br /> <<img src="static/image/smiley/default/titter.gif" smilieid="9" border="0" alt="" />><FONT color=#000000> （1）入瞳对轴上光束应全通过，轴外光束允许有渐晕。这就是对其大小的要求。<br /> （2）入瞳距应允许在较大范围变动，这有利于搜索最好的光栏位置，方法如下：<br /> 给定入瞳大小（常量），入瞳距以变动范围。先手动改动入瞳距，观察成象面处光束汇集情况。可以用移动入瞳距和改变最大口径上下光渐晕的方 法（点击工具钮“Fie”，改变VDY值，即改变了主光在入瞳面的子午高度 ，这相当于改变了入瞳距，改变最大视场VCY值，即改变了最大视场的入瞳</FONT><FONT color=#000000>的</FONT><FONT color=#000000> 子午方向的相对口镜，这就是轴外渐晕）。改动这两个量的同时，一定要注意观察象面成象光束的结构状况，使在调整上述两个参数VDY，VCY使成象不好的光束被拦切。这样就可大致确定较好的入瞳位置。然后辅以自动设计（给入瞳以正负变动范围）就可以了。</FONT></P><br /> <<img src="static/image/smiley/default/titter.gif" smilieid="9" border="0" alt="" />>2 是否真实镜头的入瞳大小和位置是有变化存在误差?.<br /> 这是显然的。一定存在偏差。这就要给半径，材料，间隔与厚度，中心偏以合理的公差（公差中要包含镜头的装配公差）。这些都会影向到入瞳大小与距离。</P><br /> <<img src="static/image/smiley/default/titter.gif" smilieid="9" border="0" alt="" />>3 是否有大的渐晕的存在.?<br /> 渐晕在数码镜头中是有要求的，最大不小于70%，极限清况不得小于60%。注意在大视场，尤其是超广角时，数码镜头出射光束主光线倾角不得大于20度。当然这些数据不是绝对的，要两个参数兼顾，给两参数分配一组合理的值（例如：最大视场渐晕是0，则最大视场主光线出射倾角允许达到25度）。</P><br /> <<img src="static/image/smiley/default/titter.gif" smilieid="9" border="0" alt="" />>4 广角和变焦适合使用吗?<br /> 广角是可以用上述方法的,因为在上法中，我们是以真实光线为依据，调整入瞳与渐晕的。<br /> 变焦清况就比较复杂。因为变焦时入瞳最大值的大小和入瞳距是在变化的，因此不存在全段统一的调整办法。应分段进行考查。好在ZEMAX变焦设计是分段给定参数的，这样我们在每段都可用上述方法进行入瞳参数的调整。<br /> 上述为一些建议，不妥处望指正。</P><br /> <<img src="static/image/smiley/default/titter.gif" smilieid="9"
