| titleOfInvention | Wide-wavelength-coverage photo-thermal deflection spectrum testing device |
| abstract | The invention discloses a wide-wavelength-coverage photo-thermal deflection spectrum testing device, which comprises a pump light source, a monochromator, an optical chopper and a beam splitter which are sequentially arranged along a light path; a photoelectric detector is arranged on a reflection light path of the beam splitter, and an absorption cell is arranged on a transmission light path of the beam splitter; the signal output end of the photoelectric detector is connected with a computer; the absorption cell is respectively provided with a detection light source and a position sensitive detector on two side surfaces which are vertical to the transmission light path of the beam splitter; the signal output end of the position sensitive detector is sequentially connected with the phase-locked amplifier and the computer; the absorption tank is used for accommodating a heat-conducting medium, the bottom of the absorption tank is fixedly provided with a sample table, and the sample table is used for fixing a film to be detected; a focusing lens is arranged between the absorption cell and the beam splitter, and the pump light transmitted through the beam splitter enters the absorption cell through the focusing lens; the pumping light source adopts laser to drive a broadband light source and is used for emitting pumping light with the wavelength of 170nm to 2100 nm. With the present invention, the testing requirements from narrow bandgap materials to wide bandgap materials can be met simultaneously. |
