Publication number: 20240410756Abstract: A proposed Raman measurement device has a housing, an optical module, and a measuring probe. The measuring probe is connected to the optical module which is installed in the housing. A part of the measuring probe protrudes from the housing. An open end of the measuring probe outputs an emitted light from a laser light source in the optical module and receives the Raman scattered light excited from a surface to be detected. The axial centerline of the measuring probe and any parallel line in the length direction of the housing include an angle of 15° to 50° and the effective focusing distance between the open end of the measuring probe and the surface to be detected is 7 mm to 9 mm.Type: ApplicationFiled: October 12, 2023Publication date: December 12, 2024Inventors: YU NIEN LU, FENG-MIN SHEN
