    Abstract: A monochromator having a corner mirror scanning wheel and a fixed baffle adjacent the scanning wheel to vary the effective height of an exit slit. The height profile of the baffle is adapted to selectively vary the radiant energy passed through this exit slit at different wavelengths so as to provide the desired balance among resolution, signal-to-noise ratio and the dynamic range of the background signal over the scanned portion of the spectrum.

    Abstract: A target for evaluating the characteristics of a thermoplastic photosensitive element is herein disclosed. The target includes a partially transparent or partially absorbing film having at least two fixed narrow bandwidth slits therein and a mask of varying optical density placed on top of or underneath the slit containing film. The target is capable of being positioned in contact with the photosensitive element to reside between the element and a source of exposing radiation. When exposed to a calibrated source of light, an image of known high frequency spatial intensity distribution surrounded by a normal sensitometric exposure results. By observing the effects of this known exposure on a developed thermoplastic photoreceptor characteristics of major concern can be determined.

    Abstract: IN MONOCHROMATORS A (COOLIMATED) INCIDENT RADIATION BEAM FROM THE ENTRANCE SLIT FALLS ON A DISPERSION MEANS AND LEAVES AS MONOCHROMATIC BEAMS, HAVING (IN GENERAL) A DIFFERENT WIDTH. IN NON-SYMMETRICAL MONOCHROMATORS, THE GREATEST RADIANT FLUX INTENSITY AT A GIVEN PREDETERMINED RESOLUTION IS OBTAINED WHEN THE RATIO OF THE EXIT SLID WIDTH TO THE ENTRANCE SLID WIDTH IS EQUAL TO: THE INCIDENT BEAM WIDTH DIVIDED BY THE WIDTH OF THAT MONOCHROMATIC DISPERSED BEAM WHICH WILL REACH THE EXIT SLID, THIS FRACTION MULTIPLIED BY THE RATIO OF THE EFFECTIVE IMAGE DISTANCE OF THE ENTRANCE SLID IMAGE (FORMED AT THE EXIT SLIT PLANE) DIVIDED BY THE EFFECTIVE OBJECT DISTANCE OF THE ENTRANCE SLIT. A MECHANICAL LINKING OF THE ENTRANCE AND EXIT SLITS IS DISCLOSED FOR SATISFYING THE ABOVE RELATIONSHIP FOR A SINGLE WAVELENGTH (NEAR THE MIDDLE OF THE WAVELENGTH RANGE UTILIZED). MORE COMPLEX BUT MORE PREFECTLY CORRECTED MONOCHROMATOR SLIT SYSTEMS WOULD MAINTAIN THIS SLIT WIDTH RELATIONSHIP AT (A) ALL WAVELENGTHS OVER WHICH THE MONOCHROMATOR IS USED, AND (B) FOR ALL SLIT WIDTHS DESIRED TO BE USED. AN EMBODIMENT OF A COMPLETE SLIT-CONTROLLING SYSTEM PROVIDES CHANGES IN THE RELATIVE WIDTHS OF THE ENTRANCE AND EXIT SLITS TO MAINTAIN THE ABOVE DESIRED RELATIONSHIP AT ALL UTILIZED WAVELENGTHS, EVEN WHEN THE ENTRANCE SLIT WIDTH ITSELF IS "PROGRAMMED" ACCORDING TO THE WAVE LENGTH OF THE MONOCHROMATOR.
