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。 G .PzpBA 单光栅(标准配置)可覆盖5-80nm测量范围 T.m*LM 技术参数 w]<a$C8*y: • u1@&o9 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 }(*eR F' 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/:l S4 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 @Rc/^B: actuators with absolute position monitoring add to the robustness and t\\oGH 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$/* E]aQK.
- Customization 5 R* The adaptability of our XUV spectrometer makes it possible to highly B.Szp_$ custom-fit the device to requirements. Thus we offer to customize every 006qj. spectrometer to exactly match the desired research application. This Xur{nk~? includes e.g. interfacing to experimental chambers, adaption of the (=jztIZC source distance, integration of customer-supplied detectors, ZyJ-}[z user-defined filter mounts, non-magnetic instruments, special mounting b +4x2{ situations, etc. $;J:kd;< t.s;dlx[@ 典型客户: N I*x):bx 1) 苏黎世联邦理工学院 w3<%wN>tE 2) The Institute of Electronic Structure and Laser of the Foundation for Research and Technology-Hellas (IESL-FORTH) S;I>W&U 3) MPQ s7 789pR 4) Los Alamos $2kZM4 5) Max Planck Institute [& d"Z2gK 上海达灿光电科技有限公司 2F
