Recalibration of Q Capability Indications from Infrared Measurements on Cultured Quartz,
Abstract
The calibrated formula reported in Sawyer '721) that predicts Q capability from measurements of extinction coefficients at 3500 1 cm has been re-examined on a broader basis. Quartz samples from four growers have been measured for infrared transmittances at the three wave numbers; 3585, 3500, and 3410, using most of the suggestions in Brice and Cole '782). In addition, matched pieces of each of the samples were made into Warner's design 5-MHz fifth-overtone resonators by one or more of five manufacturers for Q-measurement use.
