More Information
Summary:The invention relates to the technical field of spectrometers and in particular to an adjustable pinhole device which comprises a fixing frame mechanism, a pinhole dial mechanism, a rotating shaft mechanism, a linear motor separating mechanism and a rotary motor mechanism. The fixing frame mechanism includes a bottom plate, a fixing frame, two limit switches, a ball, and a fixing frame large magnet. The fixing frame is fixed to the upper part of the bottom plate by bolts. The ball and the fixing frame large magnet are fixedly pasted in corresponding grooves on the fixing frame. The middle partof the fixing frame is equipped with a central hole. One side of the central hole is provided with a side hole communicating with the central hole. The two limit switches are installed on the bottomplate through limit switch seats. The adjustable pinhole device can receive Raman scattering light focused on a pinhole by adjusting different hole pitches in combination with a confocal optical pathsystem, and can calculate t
