Product Introduction This compact and low-cost NE-1 calibration light source is suitable for wavelength calibration of visible and near-infrared spectra. The NE-1 can generate transmittance spectral lines in the range of 540-754 nanometers, making it suitable for fast and reliable wavelength calibration of spectrometers. NE-1 can be used to confirm the wavelength accuracy of any spectrometer and can also be used for recalibration of the spectrometer if necessary. NE-1 operates with a 220VDC power supply (included in the product). It can be equipped with any SMA fiber or FC fiber to connect with NE-1.
