RULING OF LARGE DIFFRACTION GRATINGS UNDER INTERFEROMETRIC CONTROL

Abstract

INCREASE IN THE QUALITY AND AVAILABILITY OF DIFFRACTION GRATINGS IS DISCUSSED, AND NEW TECHNIQUES WHICH WOULD MAKE POSSIBLE THE PRODUCTION OF GRATINGS HAVING HIGHER RESOLVING POWER, DISPERSION, SPEED, AN USEFULNESS THAN THOSE PREVIOUSLY AVAILABLE ARE TREATED. The gratings described have been designed principally for use in the visible and ultraviolet regions of the spectrum, although important applications in the infrared and far ultraviolet are expected. Plane gratings up to 10-inches in width, with resolution much higher than any previously available, were ruled only weak satellite and ghost defects. A number of master gratings have been produced from which replicas have been produced commercially, and the demand for gratings from M.I.T. ruled masters now far exceeds the supply. (Author)
