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 expression of F-P etalon transmissivity is derived for two surfaces that make up an F-P etalon that have different reflectivities and also include absorption losses. When both surfaces have the same reflectivity while ignoring the absorption loss, the general expression transitions to the usual expressions in literature or books. When the two surfaces have different reflectivities while ignoring the absorption, it is found that the maximum transmission in this case is no longer 100%, but a certain reflection, and the greater the difference between the reflectivities of the two surfaces The more obvious the impact.
