Method and devices for the chromatic analysis of an object
Abstract
Abstract A METHOD FOR THE CHROMATIC ANALYSIS OF AN OBJECT INCLUDING FOCUSING A BEAM OF LIGHT FROM THE OBJECT ONTO A CONCAVE DIFFRACTION GRATING WHERE AN IMAGE IS FORMED, THE BEAM IS THEN DIRECTED TO A MASKED SPHERICAL MIRROR HAVING AT LEAST ONE APERATURE THEREIN, WHICH THEREBY SELECTS AT LEAST ONE BAND OF WAVELENGHTS WHICH IS REFLECTED ONTO A RECEIVING SURFACE. A CHROMATIC ANALYSIS DEVICE OF TO THE PRIMARY COLORS AND THE IMAGE IS RECONSTITUTED ON TO THE PRIMARY COLORS AND THE IMAGE IS RECONSTITUTED ON THE SCREEN OF AN ELECTRON BEAM TUBE. A PLURALITY OF LENSES ARE DISPOSED BETWEEN THE MASKED MIRROR AND THE SCREEN FOR FOCUSING THE RECONSTITUTED IMAGE THEREON. THE DEVICE MAY BE USED FOR SPECTROPHOTOMETRY WHEREIN THE FOCUSING DEVICE EMPLOYED IS AN APERATURED DIAPHRAGM WITH A SPHERICAL MIRROR. THROUGHOUT, THE FOCUSING DEVICE AND THE MASKED MIRROR ARE LOCATED ON THE ROWLAND CIRCLE OF THE DIFFRACTION GRATING.
