Abstract
IN the region 3–4, the dispersive power of crystal line quartz (ordinary ray) is about four times that of fluorite and thirteen to fourteen times that of rock-salt, but, because of strong absorption beyond 3.6 and also between 2.8 and 3.1, quartz has been neglected as a prism material in this part of the spectrum. The high dispersive power does, never theless, more than compensate for the loss due to absorption, and better resolution is obtainable than with nuorite.
