In IR spectometer no lamp will be used.
IR radiation is produced by electrically heating an inert
solid material in the temperature range of 1500-2000k.The
heated material then emits IR radiation.
Ex: 1. Nernest glower - A cylinder of rare earth oxides
2200 k temperature
2. Glober - Silicon carbide rod 1500 k temp
3. Incandescent wire
4. Nichrome
5. Light emitting diodes
Other natural sources are sun,fire. IR is one of the light
emitting from these
