FOURIER TRANSFORM INFRARED SPECTROPHOTOMETER

摘要

PURPOSE:To improve the detection efficiency by arranging a diffusive reflection optical system in the optical path between the interference optical system and an interference luminous flux detector section. CONSTITUTION:Light from a light source 1 is sent to an interference optical system 3 after turned to a parallel light by a luminous flux parallel optical system 2. A diffusive reflection device 4 is arranged between the interference optical system 3 and an interference luminous flux detector section 5 and a sample 4' is placed. With such an arrangement, the sensitivity and resolution are improved.
