A model is developed for rays passing through a simulated germanium (Ge) hemisphere attenuated total reflection (ATR) microscope. The model determines a data set for rays reaching the detector plane. Movement of the hemisphere is simulated along a first axis between each data set determination. A calculated background spectrum is produced by multiplying the percentage of rays by a background spectrum to produce a calculated background spectrum. A real Ge hemisphere ATR microscope having parameters that substantially match those of the simulated Ge hemisphere microscope is then used to collect a chemical image of a sample that is in contact with the Ge hemisphere. The collected image is then corrected to produce a corrected chemical image."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Correction of chemical image collected using ATR through germanium hemisphere","description":"A method and corresponding apparatus provide correction of chemical images collected with a germanium hemisphere ATR microscope.
