FIELD: measurement technology.
SUBSTANCE: proposed radiation source has resonance-line radiators disposed in tandem along single optical line. Used as radiators is set of electrodeless lamps having individual characteristic radiation resonance lines affording shaping of desired set of resonance lines. All lamps are provided with common adjustable excitation source for brightness control, or each electrodeless lamp is provided with adjustable excitation source for controlling luminous intensity of lamp.
EFFECT: enhanced measurement stability, facilitated manufacture.
