Calculations of radiant heating by inhomogeneous hot gases require knowledge of spectral transmittances of inhomogeneous optical paths. Determination of these transmittances is a difficult problem that can be attacked by means of the Curtis-Godson approximation, which replaces each inhomogeneous optical path with a hypothetical homogeneous path that has the same transmittance. The authors have ...

Films of transparent semiconductors are widely studied and developed because of high potential applications in electronics in last decade. Our work concerns the properties of NiO films fabricated by RF magnetron sputtering. Electrical and optical parameters of the films were characterized using Hall and transmittance measurements, respectively. P-type conductivity of as-deposited films and afte...

The optical transmittance of the commonly used Cerenkov counter gases, Freon 12, Freon 13; C02, SF8, and N2, was measured in the range from 1875 A to 8000 A, and normalized for a 100 cm X 1 atm path. Calculations of efficiency for Cerenkov counters, particularly threshold type, require a knowledge of the optical transmittance of the counter filling for the Cerenkov light. For many of the gases ...

A green windshield at night reduces acuity from 20/32 to 20/46, and combined with pink glasses to 20/60. Resolution thresholds decreased from 10 to 42 seconds of arc, so that a pair of objects that could be seen through a clear windshield at 100 feet decreased to 25 feet through the green. Other visual functions found "defective in night-driving conditions with tinted glass" were stereo acuity,...

A high transmittance polymer-stabilized blue-phase liquid crystal display with floating electrodes in conjunction with protruded electrodes is proposed. The floating electrodes help to confine the electric field and reduce the dead zone areas. As a result, the peak transmittance over 90% is achieved. Author

This article describes how the dimensions of nanowires affect the transmittance and sheet resistance of a random nanowire network. Silver nanowires with independently controlled lengths and diameters were synthesized with a gram-scale polyol synthesis by controlling the reaction temperature and time. Characterization of films composed of nanowires of different lengths but the same diameter enab...
