| 摘 要： | 为了提高Fresnel菱体延迟器的消色差性能,通过对各个参数进行分析,得出了结构角α的关系式。结果表明,设计的延迟器件在550nm-1240nm的光谱范围内最大延迟误差小于1°,这一结果对设计λ/4消色差廷迟器是非常有帮助的。

| Abstract: | In order to heighten achromatic performance of Fresnel retarders, all parameters were analyzed, and expression of structure angle was obtained. It was shown within the range of 550nm to 1240nm that the maximal delay errors were smaller than 1°,so the result was helpful to designλ/ 4 achromatism retarders. |
