    Portable Raman Spectrometers

    405nm Portable Raman Spectrometers

    ModelLHU-405
    BrandGlit
    PlaceShenzhen

    • LHU-405, produced by Glit, employs a 405nm laser diode as an excitation light source and a fiber spectrometer as Raman spectrum detection module. A unique optical design and a wonderful approach eliminating stray light enable Raman probe, connected to 405 laser diode source and the spectrum detection module respectively through two fibers, to obtain the materials’ Raman signal with both high coupling efficiency and high signal to noise ration. A computer that controls LHU-405  is mounted on top of the portable casing. Software of LHU-405 developed by Glit carries out functions of the laser control, Raman spectrum detection, database management and material analysis etc., which greatly help users to conveniently fulfill Raman spectrum analysis. LHU-405 is a wonderful portable Raman spectrometer featuring without direct contact to materials, compact structure, easy operation, multiple applications and good performance etc. 


    • 405nm excitation laser, high end light detector, grating spectroscopy.

      Optical probe emits laser with a high output coupling efficiency. 

      Non-contact Raman spectral measurement and analysis.

      Software has the functions of laser control, Raman spectroscopy, database management, background substance and log (recording of experiment’s content ) etc.

      Mass production for industrial applications with excellent thermal stability and vibration resistance.

      Easy to carry and use.
