NEW MODEL 6 2 1 I R SPECTROPHOTOMETER PROVIDES OPTIMUM ENERGY TRANSFER OVER ENTIRE 4000-200 CM RANGE In the Model 621 Filter-Grating* Infrared Spectrophotometer, Perkin-Elmer — world leader in infrared —has achieved a new level of performance over the instrument's total operating range: from 4000 to 200 cm" 1 . Fundamental to this additional per- formance is greater utilization of avaiiabfe energy, even where low energy is classi- cally a problem.To do this,Perkin-Elmer has • widened the slit opening capability to optimize performance under low energy conditions; • enlarged the size of the Nernst giower source for greater total energy; • utilized aspheric (toroidal, paraboloidal) optics for most efficient transfer of energy, and precise imagery—a Perkin-Elmer exclu- sive feature; • redesigned the thermocouple detector target for greater sensitivity over the total range; • maintained Perkin-Elmer's unique, fast f/4.5 optical system, with short paths for efficient and rapid purging. These features provide an energy bonus and increase the optical precision of the Model 621's system. Thus, they enhance a traditional Perkin-Elmer advantage: the unique capacity to perform microanalysis to an unequalled degree of sensitivity. No matter whether the sample is limited, or the component of quantitative interest is present only as the fractional part of a microgram, Perkin-Elmer's total system is geared to provide a quick, easy and pre- cise determination.

NEW MODEL 621IR SPECTROPHOTOMETER PROVIDES OPTIMUM ENERGY TRANSFER OVER ENTIRE 4000-200 CM RANGE In the Mode l 621 F i l ter -Grat ing* Infrared Spectrophotometer, Perkin-Elmer — w o r l d leader in infrared —has achieved a new level of performance over the instrument's tota l operat ing range: f rom 4000 to 200 cm"1. Fundamental to this add i t iona l per

• w idened the slit opening capabi l i ty t o opt imize performance under low energy condit ions;
• enlarged the size of the Nernst g iower source for greater total energy;
• ut i l ized aspheric ( toroidal , parabo lo ida l ) optics for most efficient transfer of energy, and precise imagery—a Perkin-Elmer exclusive feature;
• redesigned the thermocouple detector target for greater sensitivity over the to ta l range;
• mainta ined Perkin-Elmer's unique, fast
