"Precision is unlimited at Bausch & Lomb when higher accuracy means a better product." THEODORE B. DRESCHEN Vice President Bausch & Lamb Optical Co.

ODERN machinery, instruments of measurement, and know-how have made it possible to achieve amazingly high degrees of accuracy in manufacturing. Infinitesimal working tolerances are uniformly maintained in regular production. Here at B&L, for example, the limit of tolerance in general use for some products is a quarter wavelength of sodium light, or 147.3 millimicrons. Widespread publication of striking examples of precision such as this have created the false impression that pre-
cision itself is the ultimate goal. Let us remember that precision is not just using a light wave as a yardstick. Theodore B. Drescher, Vice-President in Charge of Manufacturing, says, "In a given product, tolerances of components may reach ± 1/1,000,000 of an inch, if performance demands it." The basic obj ective of Bausch & Lomb precision is to obtain whatever degree of accuracy in manufacture or measurement is dictated by t h e product's FUNCTIONAL EFFICIENCY . . . no matter how high.
