Abstract

A new scanning spectrometer is described herein which is based almost exclusively on very recent technological advances and which, over the ultraviolet, visible, and near infrared region to 6 microns is capable of resolution and wavelength measuring accuracy comparable, on a wave-number basis, with the best that has been accomplished with spectrographs limited to the photographic region. The instrument is of the Ebert type and employs gratings as large as 5×7 inches, has a focal length of 72 inches, uses circularly curved slits 2 inches long, and can be triple passed. Specifications and performance are outlined.
