技术优势介绍: cN)noGkp - Direct imaging of the source / Superior signal strength ^L'<%_#. In contrast to conventional devices our XUV spectrometer does not ]K<7A!+@@p require a narrow entrance aperture but rather images the harmonic source ##U/Wa3 directly onto the detector. Thus 80% or more of the incoming beam can be 1c`Yn:H^ used for measurement. Please see mQ\oR| http://www.hoerlein-partner.com/#!services/cihc for a sketch drawing. yRz l} This configuration typically collects 15 to 25 times more light than "p&4Sn3T2? standard versions, resulting in a signal-to-noise figure improved by the +sXnC\ same ratio. B:)vPO+ d In some experiments, this improved signal strength is the crucial step H#QPcp@ for realizing a measurement at all. YV6w}b: ^!SwY_> - Flat-field imaging technology {tnhP^C3> Our instruments are based on high quality aberration-corrected Rtai? flat-field gratings. In contrast to conventional gratings these focus KzB9
mMrO all wavelengths onto a plane rather than a circle. This allows for yI's=Iu` positioning the entire detector in the focal plane of the grating for ?$b*)< superior spectral resolution. 'he&h4fm 83Fmu/( - Compactness / Modularity 7Y^2JlZu= The spectrometer is very compact and can be bolted directly to a vacuum I5g!c|#y
chamber. It is capable of carrying its own weight, no table required. pwV{@h! There are no externally moving parts. i.+#a2 Through its modular design, our spectrometer can be adapted to a number x%RE3J- of configurations (source distance, spectral range, detectors, vacuum Ft8ii|- pumping, etc). This makes it highly flexible for varying requirements ;zi4W1 and experiments. fJn4'Q*U z!^3%kJJ> - Robust against misalignment SuA`F|7?P The compact design of the spectrometer makes it inherently insensitive `e5f69" against mechanical and environmental disturbances (vibrations, ?gS~9jgcd acoustics, etc). No externally moving parts and closed-loop grating OWmI$_L actuators with absolute position monitoring add to the robustness and =7zvp,B allow for monitoring of the grating alignment at all times. ,
ins/-3 In addition, the concept of a spectrometer without entrance slit also s?&UFyYb, makes the instrument less sensitive to misalignment. Under typical |exjrsmM* operating conditions a misalignment of the beam in the dispersion BR0P :h direction on the entrance of the spectrometer by 500um would lead to a >orDw3xC signal reduction by more than 20% in an instrument with entrance slit e'dZ2;X$zo while it is less than 10% for our design. <Kq!))

This QBTjiaYGa' includes e.g. interfacing to experimental chambers, adaption of the C-VkXk source distance, integration of customer-supplied detectors, `wLMJ,@f. user-defined filter mounts, non-magnetic instruments, special mounting efm#:>H situations, etc. -[>G@m:?e S d]`) 典型客户: (%|L23 1) 苏黎世联邦理工学院 NSQf@o 2) The Institute of Electronic Structure and Laser of the Foundation for Research and Technology-Hellas (IESL-FORTH)
