- Direct imaging of the source / Superior signal strength d0ThhO
In contrast to conventional devices our XUV spectrometer does not ++n"`
]o,
require a narrow entrance aperture but rather images the harmonic source YUU |!A8x
directly onto the detector. Thus 80% or more of the incoming beam can be 64;F g/t
used for measurement. Please see kY*3)KCp

This configuration typically collects 15 to 25 times more light than ~V&4<=r`
standard versions, resulting in a signal-to-noise figure improved by the .|[ZEXq
same ratio. @ FVan
In some experiments, this improved signal strength is the crucial step px;5X4U
for realizing a measurement at all. h fT HP

- Flat-field imaging technology ivg:`$a[
Our instruments are based on high quality aberration-corrected p?(w ! O
flat-field gratings. In contrast to conventional gratings these focus 7OY<*ny
all wavelengths onto a plane rather than a circle. This allows for ^HYmi\`
positioning the entire detector in the focal plane of the grating for Tap=K|b ]
superior spectral resolution. 5[l9`Cn&A

- Compactness / Modularity sf )ojq6s
The spectrometer is very compact and can be bolted directly to a vacuum S-V)!6\cK
chamber. It is capable of carrying its own weight, no table required. 4Kjrk7GAx
There are no externally moving parts. ReE-I/n8f
Through its modular design, our spectrometer can be adapted to a number .J :04t1
of configurations (source distance, spectral range, detectors, vacuum ~>u]ow=
pumping, etc). This makes it highly flexible for varying requirements Ah:!

- Robust against misalignment l9"4"+ ?j<
The compact design of the spectrometer makes it inherently insensitive }% (e`[?1
against mechanical and environmental disturbances (vibrations, 3 ]xe7F'`
acoustics, etc). No externally moving parts and closed-loop grating [=M0%"
actuators with absolute position monitoring add to the robustness and k[lYd k
allow for monitoring of the grating alignment at all times. %\6ns
In addition, the concept of a spectrometer without entrance slit also @V{s'V
makes the instrument less sensitive to misalignment. Under typical 62lG,y_L
operating conditions a misalignment of the beam in the dispersion N2:};a[ui5
direction on the entrance of the spectrometer by 500um would lead to a YI0 5?J}
signal reduction by more than 20% in an instrument with entrance slit M`IiK+IoU

- Customization lU]/n Kyd
The adaptability of our XUV spectrometer makes it possible to highly 3C'`c=
custom-fit the device to requirements. Thus we offer to customize every vlYDhjZk#
spectrometer to exactly match the desired research application. This |O0=Q,<m
includes e.g. interfacing to experimental chambers, adaption of the W+k`^A|@
source distance, integration of customer-supplied detectors, ZqKUz5M4
