COMPLETE chemistry of metals including carbon, sulphur The Baird-Atomic Spectrovac incorporates new princi ples of optical, mechanical and electronic design to give metallurgy its most versatile analytical instrument. Covering a wavelength range from 1450 — 4300A, with linear reciprocal dispersion of 2.76 A/mm, the Spectrovac permits observation of more sensitive lines, with higher resolution, than any other Schumann region apparatus. Only the Spectrovac offers Rowland-mounted optics which assure both maximum linearity and perfect sym metry of dispersion. The patented Automatic Servo Monitor insures continuous optical alignment. The high vacuum maintained within the chamber permits 99.99% transmission of the vacuum region wavelengths. A D V A N C E D
