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。 r1F5'?NZ(0 单光栅(标准配置)可覆盖5-80nm测量范围 1q;R+65 技术参数 yWN'va1+$ • M_?B*QZJI 技术优势介绍: vPZ0?r_5W - 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 *!NW!,R http://www.hoerlein-partner.com/#!services/cihc for a sketch drawing. cy8r}wD This configuration typically collects 15 to 25 times more light than standard versions, resulting in a signal-to-noise figure improved by the : @gW3' same ratio. dn%'bt In some experiments, this improved signal strength is the crucial step for realizing a measurement at all. zEE:C|50 't\sXN+1 - Flat-field imaging technology 1?TgI0HS 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. 'w;J)_Yc2 #5{lOeN - Compactness / Modularity B( wi+; The spectrometer is very compact and can be bolted directly to a vacuum chamber. It is capable of carrying its own weight, no table required. DfOigLG* There are no externally moving parts. I$TD[W Through its modular design, our spectrometer can be adapted to a number of configurations (source distance, spectral range, detectors, vacuum !cO<N~0*5x pumping, etc). This makes it highly flexible for varying requirements and experiments. =*?XZA)c Ko0T[TNkh - Robust against misalignment .?F`H[^)^u The compact design of the spectrometer makes it inherently insensitive against mechanical and environmental disturbances (vibrations, +b dnTV6 acoustics, etc). No externally moving parts and closed-loop grating actuators with absolute position monitoring add to the robustness and JS >"j d# allow for monitoring of the grating alignment at all times. m}m|(;T In addition, the concept of a spectrometer without entrance slit also makes the instrument less sensitive to misalignment. Under typical 61b<6r0o operating conditions a misalignment of the beam in the dispersion direction on the entrance of the spectrometer by 500um would lead to a >BMtR0 signal reduction by more than 20% in an instrument with entrance slit while it is less than 10% for our design.
