Abstract:

Selective reflection from mercury vapor at oblique incidence is studied at 2537A. A narrowband optical vapor filter based on oblique specular reflection from vapors is described. The device consists of a mercury vapor cell with Brewster angle windows which selectively reflects the 2537A line and transmits other radiation. The bandwidth of the device varies from 0.1A to 1.0A as a function of the mercury vapor pressure. It is used to perform a spectrochemical analysis of mercury in water and also to take a monochromatic photograph of the spatial distribution of excited mercury atoms in a flame.
