Polyimides are a class of materials composed of imide monomers. The optical properties of polyimides vary widely depending on their composition and synthesis method. DuPont has developed several polyimides which they sell under the trade name Kapton. Many other companies sell polyimides. Due to the drastically different optical properties of various polimides, there are several different material data files, each of which is identified by the refractive index at 632 nm.

对于典型的样品 - Polyimide - n=1.89 - 波长在 632.8 nm 下的折射率和消光系数为1.88552及0.0009496966。 以下是包含完整折射率和消光系数的文件。 如果文件无法下载，请点击“请求”（Request）以索取该专有文件。
