Aurora4000 UV-NIR Fiber Optic Spectrometer

 

Aurora4000 spectrometer is developed by Jilin Lasertech Opto-Mechatronics equipment Co., Ltd. With 3648 pixels CCD linear array detector, it has high resolution up to 0.02 nm (FWHM). The system includes incident slit, collimating mirror, dispersion element (grating), focusing optical system and detector. Light is collected  through the optical fiber into the spectrometer slit then the spectral information can be read out by the software.


Features:

  • Wide range

  • Broadband

  • High resolution

  • Robust package

Applications:

  • Spectral analysis

  • Wavelength inspection

  • Absorbance measurements

  • Reflectivity measurements

  • LED analysis
