The F/1.8 quartz monochromator-spectrograph

Joseph W. Perry

Open publisher page 4 citations

Abstract

The circumstances in which large monochromators and spectrographs of especially high illuminating power are requisite are discussed and the dependence of illuminating power and instrument efficiency upon the essential optical characteristics of such instruments is investigated. A description is given of a large instrument fulfilling the combined functions of monochromator and spectrograph, the relative aperture of which varies from F /1.6 at 0.185 to F /2.0 at 1.2μ, and records of performance are described.
