Abstract

PURPOSE:To lead pumping light to resonance cell effectively, by enabling filter cell to have an effect of lens. CONSTITUTION:As glass wall surface of a filter cell 15 is composed of flat-and- convex lens, a light radiated from a lamp 2 is deprived of unnessary spectro element by the filter 15, focussed and effectively radiated onto a resonance cell 4. For this reason, Rb standard can be easily reduced in size, and also such problems as increase of noise of spector and shortening of a lamp's service life, etc. by S/N ratio and overexcitation can be solved.
