技术优势介绍: B;[ai?@c(_  
- Direct imaging of the source / Superior signal strength dCbRlW  
In contrast to conventional devices our XUV spectrometer does not :[hZn/  
require a narrow entrance aperture but rather images the harmonic source =IbDGw(  
directly onto the detector. Thus 80% or more of the incoming beam can be }(*eRF'  
used for measurement. Please see `,-w+3?Al  
http://www.hoerlein-partner.com/#!services/cihc for a sketch drawing. 4V2}'/|[  
This configuration typically collects 15 to 25 times more light than H]^hEQ3DT  
standard versions, resulting in a signal-to-noise figure improved by the I-L52%E]  
same ratio. 6a_MA*XK  
In some experiments, this improved signal strength is the crucial step {=Z xF  
for realizing a measurement at all. tBJCfM  
n\X'2  
- Flat-field imaging technology ]g/:lS4  
Our instruments are based on high quality aberration-corrected @e`%'  
flat-field gratings. In contrast to conventional gratings these focus A }(V2  
all wavelengths onto a plane rather than a circle. This allows for !xqy6%p  
positioning the entire detector in the focal plane of the grating for %MA o<,ha  
superior spectral resolution. Z4&,KrV  
*9XKkR<r  
- Compactness / Modularity [ 2WJ];FJ  
The spectrometer is very compact and can be bolted directly to a vacuum NU]+ {7  
chamber. It is capable of carrying its own weight, no table required. !+<OED=qe  
There are no externally moving parts. [UP-BX(  
Through its modular design, our spectrometer can be adapted to a number %S'gDCwq  
of configurations (source distance, spectral range, detectors, vacuum qdss(LZ  
pumping, etc). This makes it highly flexible for varying requirements v--Qbu  
and experiments. xOKLc!J  
||xiKg  
- Robust against misalignment nBN+.RB:(  
The compact design of the spectrometer makes it inherently insensitive u!]g^r  
against mechanical and environmental disturbances (vibrations, X-lB1uq^  
acoustics, etc). No externally moving parts and closed-loop grating @R c/ ^B:  
actuators with absolute position monitoring add to the robustness and t\\oG H  
allow for monitoring of the grating alignment at all times. QsO%m  
In addition, the concept of a spectrometer without entrance slit also <6!;mb ;cX  
makes the instrument less sensitive to misalignment. Under typical yF [|dB  
operating conditions a misalignment of the beam in the dispersion }|KNw*h $  
direction on the entrance of the spectrometer by 500um would lead to a %z9lCTmy  
signal reduction by more than 20% in an instrument with entrance slit <~d3L4h*<  
while it is less than 10% for our design. /i[1$/*

- Customization 5 R*  
The adaptability of our XUV spectrometer makes it possible to highly B.Szp_$  
custom-fit the device to requirements. Thus we offer to customize every 006 qj.  
spectrometer to exactly match the desired research application. This Xur{nk~?  
includes e.g. interfacing to experimental chambers, adaption of the (=jztIZ C  
source distance, integration of customer-supplied detectors, Zy J-}[z  
user-defined filter mounts, non-magnetic instruments, special mounting b +4x2{  
situations, etc. $ ;J:kd;<
