:
The tungsten filament used in these heaters is the porcupine or star type coil, which can be operated at temperatures up to 1500°C (2732°F), with peak wavelength emissions of approximately 1.6 microns. It reaches top temperatures within seconds.
As well as having excellent structural rigidity, this coil is designed to minimize light output and maximize IR emission thereby increasing IR radiant efficiency.
