TEMPERATURE MEASURING DEVICE USING MICRO RAMAN SPECTROPHOTOMETER

摘要

PURPOSE:To provide a temperature measuring device provided with a micro Raman spectrophotometer which can accurately acquire temperature of a sample through simultaneous measurement of strength of Stokes Raman light and anti-Stokes Raman light and two-dimensionally display the measurement result. CONSTITUTION:An optical system of a Raman spectrophotometer is constituted by an optical means having a lens system 3 for irradiating a sample 6 with a laser beam 2 from a laser beam source 1, a half mirror 4 and an objective lens 5, a dynamic mirror 40 with such optical characteristics that either one of Raman lights of a Stokes light and an anti-Stokes light transmitting through a notch filter 41 with a light eliminated is reflected and the other is transmitted, and a one-dimensional or two-dimensional detector arranged on each optical path of the transmitted light and the reflected light. Moreover, a band-pass filter 42 is arranged on the light paths for selectively transmitting each Raman light peak so as to further improve spectroscopic performance.
