Application scope of three-element compound achromatic λ/4 wave-plate

摘要: 为了精确得到三元结构的λ/4消色差复合波片的消色差范围,采用数学解析的方法进行了理论分析,并在中心波长600nm处进行实验,得到偏差在2%以内的光谱范围大约为540nm～680nm.结果表明,其消色差范围只在中心波长的附近,这一结果对实验中棱镜的选用是有帮助的.

Abstract: In order to find the achromatic scope of three-element compound λ/4 wave-plate,mathematical analysis was performanced and experiments at the center wavelength of 600nm was executed.In the experiment the spectrum range was between 540nm~680nm when the deviation is less than 2%.It is concluded that the achromatic scope is only near the center wavelength,which is very important for practiceal prism selection.
