A Globar is used as thermal light source for infrared spectroscopy. The preffered material for making Globar is silicon carbide that is shaped as rods or arches of various sizes. When inserted into a circuit that provides it with electric current, it emits radiation from ~ 2 to 50 micrometres wavelength via the Joule heating phenomenon. Globars are used as infrared sources for spectroscopy because their spectral behavior corresponds approximately to that of a Planck radiator (i.e. a black body). Alternative infrared sources are Nernst lamps, coils of chrome–nickel alloy or high-pressure mercury lamps.

| - Globar je tyčinka z karbidu křemíku, elektricky vyhřívaná na teplotu 1000-1650 °C. Využívá se jako zdroj infračerveného záření pro infračervenou spektroskopii. (cs)
- Globar ist als Warenzeichen für Widerstands-Heizelemente aus Siliziumcarbid in den allgemeinen Sprachgebrauch gelangt. Mit solchen Heizelementen lassen sich auch an Luft (Sauerstoffeinfluss) vergleichsweise hohe Temperaturen erreichen. Globars werden auch als Strahlungsquelle im mittleren und fernen Infrarot verwendet. (de)
- Il globar o sorgente Globar è una sorgente luminosa (radiazione termica) usata in spettroscopia infrarossa. È costituito da un cilindro di carburo di silicio di 5 mm di diametro e 50 mm di lunghezza. La bacchetta viene attraversata da corrente elettrica ed emette radiazione luminosa con maggiore intensità nell'infrarosso alla temperatura di circa 1500 °C. (it)
- Глоба́р — источник инфракрасного излучения. Представляет собой стержень из карбида кремния диаметром 5 мм и длиной порядка 40 мм, нагреваемый пропускаемым через него электрическим током до температуры порядка 1200—1400 °C. Рабочий диапазон излучения глобара 0.8—25 мкм. Используется в качестве источника излучения непрерывного спектра в спектроскопии. (ru)

Globars are used as infrared sources for spectroscopy because their spectral behavior corresponds approximately to that of a Planck radiator (i.e. a black body). Alternative infrared sources are Nernst lamps, coils of chrome–nickel alloy or high-pressure mercury lamps. The technical term Globar is an English portmanteau word consisting of glow and bar. The term glowbar is sometimes used synonymously in English (which is an incorrect spelling in the strict sense). The American Resistor Company in Milwaukee, Wisconsin, had word and lettering Globar registered as a trademark (in a special decorative script font) with the United States Patent and Trademark Office on June 30, 1925 (registration number 0200201) and on October 18, 1927 (registration number 0234147). This registration had been renewed for the third time in 1987 (by various companies throughout 60 years). (en)
