visible spectrum from 400 to 700 millimicron wavelength.
T h e A O S P E C T R O P H O T O M E T E R traces 60 separate curves per second on the face of a cathode ray tube fusing them into a "moving picture" of color changes over the entire A roomy sample chamber accommodates transparent samples up to 100mm thick. A reflection attachment will produce data from opaque surfaces as small as 1 inch square.
