Thorlabs' broadband light sources cover the ultraviolet to the long-wave infrared portions of the electromagnetic spectrum, and we have options that couple into free space, fibers, or liquid light guides. The incoherent sources are stabilized to ensure long-term stability for spectroscopic measurements. We also offer a neon spectral lamp, which can be used in applications that require wavelength calibration. The Mid-IR Supercontinuum Laser and Long-Wave Supercontinuum Laser are high-brightness coherent sources in the infrared, ideal for spectroscopic applications.
