IdealPhotonics' Broadband Sources & Spectral Lamp are two types of optical devices. Broadband Sources provide continuous radiation over a wide wavelength range (such as supercontinuum lasers), while Spectral Lamps emit characteristic spectral lines of specific elements (such as mercury lamps and sodium lamps). Together, they are used for spectral calibration, material excitation, or system testing.Complementary spectral coverage requirements—Broadband Sources achieve broad-spectrum uniform excitation, while Spectral Lamps provide atomically precise spectral lines. They respectively meet the key requirements of continuous scanning and wavelength calibration.
