Abstract: A windowless microbolometer for use in terrestrial applications and non-terrestrial applications is provided. The windowless microbolometer array may interact with a flow of gas such that a pixel-based image of the gas is generated when the flow of gas impinges upon the windowless microbolometer array. The windowless microbolometer array may also interact with a molecular beam to provide information related to density, shape, and propagation of the molecular beam.

Abstract: A photographic element comprises a support bearing two or more silver halide emulsion image-forming layers each containing ultrathin tabular grains or a support bearing at least three image-forming layers for forming images of different color in which at least one of the layers contains ultrathin tabular grains, wherein the imaging silver contained in the total of all the image-forming layers of the element is as described in subparts (1), (2) and (3):(1) ultrathin tabular grains, having a thickness of less than 0.07 microns, comprise at least 25 wt % of the total imaging silver content of subparts (1), (2), and (3);(2) (a) tabular grains of thickness at least 0.10 microns and (b) non-tabular grains having an ECD of at least 0.15 microns and less than 0.70 microns, comprise not more than 50 wt % of the total imaging silver content of subparts (1), (2), and (3); and(3) tabular grains having a thickness of at least 0.07 microns and a thickness less than 0.
