XUV光谱仪
XUV光谱仪是新型的像差校正平场入射X射线光谱仪,光谱范围可涵盖1-80nm.模块化设计,可以满足不同的实验条件和环境。 dY8 H2; 单光栅(标准配置)可覆盖5-80nm测量范围 'S`l[L:.8 技术参数 UC`h o%OBF • \K$\-]N+ 技术优势介绍: |8` }8vo) - Direct imaging of the source / Superior signal strength In contrast to conventional devices our XUV spectrometer does not require a narrow entrance aperture but rather images the harmonic source directly onto the detector. Thus 80% or more of the incoming beam can be used for measurement. Please see f^pBXz9&= http://www.hoerlein-partner.com/#!services/cihc for a sketch drawing. k4{!h?h This configuration typically collects 15 to 25 times more light than standard versions, resulting in a signal-to-noise figure improved by the xlv(PVdn same ratio.

y Our instruments are based on high quality aberration-corrected flat-field gratings. In contrast to conventional gratings these focus all wavelengths onto a plane rather than a circle. This allows for positioning the entire detector in the focal plane of the grating for superior spectral resolution. ka_m
