Globar light source
WebOther articles where Globar lamp is discussed: spectroscopy: Infrared instrumentation: …the standard source is a Globar (50–6,000 cm−1), a silicon carbide cylinder that is electrically heated to function as a blackbody radiator. Radiation from a mercury-arc lamp (10–70 cm−1) is employed in the far-infrared region. In a grating-monochromator type … WebA Globar is a silicon carbide rod of 5 to 10 mm width and 20 to 50 mm length which is electrically heated up to 1000 to 1650 °C (1800 to 3000 °F) with a downstream variable interference filter that emits radiation from 4 to 15 micrometres wavelength. Globars are used as thermal light sources for infrared spectroscopy because their spectral ...
