光学系统校正像差的谱线选择，主要决定于使用条件和光能接收器的特性。光学系统要校正单色像差的波长和校正色差的波长主要取决于光接收器的光谱响应性能，但往往要受光源和光学<a href="http://material.oecr.com" target="_blank" class="relatedlink">材料</a>的限制。设计时应使接收器、光源和光学材料三者的性能匹配好，即尽可能使接收器响应最灵敏的谱线是光源辐射最强的谱线，也就是光学材料透过率最好的谱线。</div><div><br></div><div> 校正像差时谱线选择的原则是：在光学系统工作的波段范围内，光学系统对接收器的光谱响应灵敏度曲线与光源辐射光谱强度分布曲线之乘积最大值所对应的波长校正单色像差，对该波段内靠近两端的二种波长校正色差。</div><div><br></div><div><section microsoft="" yahei",="" simsun;="" margin:="" 0px;="" padding:=""
