The traditional tandem Wadsworth mounting is originally designed to match the coaxial telescope and large-scale imaging spectrometer. When it is used to connect the off-axis telescope such as off-axis parabolic mirror  it presents lower imaging quality than to connect the coaxial telescope. It may also introduce interference among the detector and the optical elements as it is applied to the short focal length and small-scale spectrometer in a close volume by satellite. An advanced tandem Wadsworth mounting has been investigated to deal with the situation. The Wadsworth astigmatism-corrected mounting condition for which is expressed as the distance between the second concave grating and the imaging plane is calculated. Then the optimum arrangement for the first plane grating and the second concave grating  which make the anterior Wadsworth condition fulfilling each wavelength  is analyzed by the geometric and first order differential calculation. These two arrangements comprise the advanced Wadsworth mounting condition. The spectral resolution has also been calculated by these conditions. An example designed by the optimum theory proves that the advanced tandem Wadsworth mounting performs excellently in spectral broadband. 2012 Optical Society of America.   Theoretical study on electronic structures and optical properties of blue phosphorescent Iridium(III) complexes with (CN)-N-boolean AND and (NN)-N-boolean AND ligands 期刊论文  OAI收割 journal of luminescence, 2013, 卷号: 143, 页码: 402-408 Shang XH; Liu YQ; Qu XC; Wu ZJ 收藏  |  浏览/下载：148/0  |  提交时间：2014/04/15 DENSITY-FUNCTIONAL THEORY  LIGHT-EMITTING-DIODES  EFFECTIVE CORE POTENTIALS  MOLECULAR CALCULATIONS  EXCITATION-ENERGIES  SPECTRAL PROPERTIES  IR(III) COMPLEXES  CHARGE-TRANSFER  EXCITED-STATES  EFFICIENCY
