ABSTRACT:
An FT-IR spectrometer (10) operated for analysis by reflectance spectroscopy, has a window (56) having a body (58) which generally transmits radiation in the visible range there through. The window has a surface (60) for supporting a sample (72) of material to be analyzed. The surface of the window has a coating (62) that generally transmits visible radiation while generally reflecting radiation across the infrared range. The window provides for fast and reliable set up of sample and background scans through use of a visual microscope portion of the spectrometer. The window also has a long life, is durable and is low in cost.
