摘要
导出了构成F-P标准具的两个表面具有不同反射率,同时包含吸收损耗在内的F-P标准具透射率一般表达式。当两个表面具有相同反射率同时忽略吸收损耗时,该一般表达式就过渡到通常文献或书籍中的表达式。而当两个表面具有不同反射率同时忽略吸收时,发现这种情况下的最大透射率不再是100%,而是有了一定的反射,同时两个表面的反射率相差越大,这种影响越明显。
The general transmission formula of F-P etalon including different reflectivity and absorption is derived. When the reflectivities of the two surfaces are the same and the absorption is ignored, the general formula will become the common formula in the documents or books. When the reflectivities are different and the absorption is ignored, the maximum transmission is not 100%, but there is a certain reflectivity. Moreover if the difference between the reflectivities of the two surfaces is bigger, the effect becomes more obvious.
