Paper Abstract

For an infrared spectrophotometer with the convergent beam in the sample compartment the stray radiation is estimated. The efficient method with different filters used to test the stray radiation is discussed. The sample-induced interreflection sources are analyzed. The method to eliminate the intereflection is introduced. It avoids the oblique errors and did not need complicated calculation. The stray radiation ratio estimations from 2.Ln to 15.tfl wavelength are less than O.4 transmittance unit. The interreflection correction improves the transmittance measurement accuracy more than ten times.
