Wavelength Calibration Lamp
The wavelength calibration light source is used for calibrating the wavelength and spectral lines of spectroscopic equipment. Its spectrum range is between 253~912 nm in the UV-visible-NIR band. The easily identifiable mercury and argon transfer spectral lines are marked on the housing, enabling quick and reliable wavelength calibration. It is a stable, long-lasting, cost-effective, and easy-to-use device. The wavelength of a fiber-optic spectrometer may slightly shift over time and due to environmental changes. If wavelength accuracy is critical for your application, consider using the wavelength calibration light source, which allows periodic wavelength adjustments and precise tuning of the fiber-optic spectrometer.
