quartz heater tube 400w have been specially developed for technical applications. They consist of a tungsten heating filament and a quartz tube. The diameter of the filament is smaller than the diameter of the quartz tube. therefore spacers/support rings are used to keep the filament in the centre of the tube which prevents the filament from direct contacting with the quartz tube. Quartz glass is highly transparent to infrared radiation up to a wavelength of 4,000 nm, which ensures that the heat radiation is emitted with minimum loss.
