技术优势介绍: mT N6-V  
- Direct imaging of the source / Superior signal strength w, 0tY=h6  
In contrast to conventional devices our XUV spectrometer does not ]+\@_1<ZI  
require a narrow entrance aperture but rather images the harmonic source MFHPh8P  
directly onto the detector. Thus 80% or more of the incoming beam can be GD1=Fb"&)  
used for measurement. Please see G?-27Jk8  
http://www.hoerlein-partner.com/#!services/cihc for a sketch drawing. uM0!,~&9|  
This configuration typically collects 15 to 25 times more light than oOk.Fq  
standard versions, resulting in a signal-to-noise figure improved by the DbSl}N;  
same ratio. NN5V|# P}  
In some experiments, this improved signal strength is the crucial step '"}|'J  
for realizing a measurement at all. 66\0JsT?3  
f~Dl;f~H_;  
- Flat-field imaging technology 7^k`:Z  
Our instruments are based on high quality aberration-corrected o{*8l#x8  
flat-field gratings. In contrast to conventional gratings these focus W>b(hVBE  
all wavelengths onto a plane rather than a circle. This allows for I`h9P2~  
positioning the entire detector in the focal plane of the grating for N" |^AF  
superior spectral resolution. {]ZZ]

- Compactness / Modularity 6y)xMX  
The spectrometer is very compact and can be bolted directly to a vacuum bAeN>~WvY  
chamber. It is capable of carrying its own weight, no table required. 8F0+\40  
There are no externally moving parts. TX{DZ#  
Through its modular design, our spectrometer can be adapted to a number u(JC 4w'  
of configurations (source distance, spectral range, detectors, vacuum qs6yEuh#  
pumping, etc). This makes it highly flexible for varying requirements jIMaP T  
and experiments. zypZ3g{vz  
<[xxCW(2  
- Robust against misalignment uR"srn;^  
The compact design of the spectrometer makes it inherently insensitive `>RJ*_aKEI  
against mechanical and environmental disturbances (vibrations, Tgp}k%R~  
acoustics, etc). No externally moving parts and closed-loop grating /_rAy  
actuators with absolute position monitoring add to the robustness and '#<?QE!d2  
allow for monitoring of the grating alignment at all times. IS7g{:}=p  
In addition, the concept of a spectrometer without entrance slit also c1wM"  
makes the instrument less sensitive to misalignment. Under typical k ]x64hgm  
operating conditions a misalignment of the beam in the dispersion =mCUuY#  
direction on the entrance of the spectrometer by 500um would lead to a k%QhF]  
signal reduction by more than 20% in an instrument with entrance slit zQ xZR}'  
while it is less than 10% for our design. w5jH#ja

- Customization 7dX1.}M<(  
The adaptability of our XUV spectrometer makes it possible to highly xc R  
custom-fit the device to requirements. Thus we offer to customize every >H@ dgb  
spectrometer to exactly match the desired research application. This e =& abu  
includes e.g. interfacing to experimental chambers, adaption of the Rs)tf|`/  
source distance, integration of customer-supplied detectors, 5(>m=ef"  
user-defined filter mounts, non-magnetic instruments, special mounting g'Ft5fQ"o/  
situations, etc. YP~d1BWvf
