Spectral lamps are commonly employed as stable, high-quality sources for identifying spectral lines even in difficult vapours and gases. When used in conjunction with narrow bandpass filters, the devices facilitate experiments where monochromatic light is necessary. Housed in closed housings and having special cooling grids, the models that generate ultraviolet radiation protect operators from the hazardous UV radiation. The spectral lamps will produce bright and pure spectrum results for easy conclusions.
