FIELD: optics. SUBSTANCE: this method is intended for monochromatization of emission of gaseous-discharge lamps in vacuum ultra-violet region of spectrum. Window of lamp is maintained at temperature 150-250 C. With line 116.5 mm appears to completely suppressed and intensity of line 123.6 mm remains invariable. Heating of window of lamp is ensured either by external heater or thanks to heat generated by operation of lamp. EFFECT: improved operational stability of characteristics. 1 dwg
