High refractive index material such as ZnSe creates fringing, which is also known as channeling. Fringes are useful for path length calibration, but fringes can also interfere with spectral analysis, particularly when the refractive index of the sample is not well matched to the refractive index of the sample. Fringing can occur in a single window where the light is reflected between parallel surfaces of window and in a cell containing a pair of windows where the light is reflected off of bothmore
