技术优势介绍:
- Direct imaging of the source / Superior signal strength
In contrast to conventional devices our XUV spectrometer does not
require a narrow entrance aperture but rather images the harmonic source
directly onto the detector. Thus 80% or more of the incoming beam can be
used for measurement. Please see
#!services/cihc for a sketch drawing.
This configuration typically collects 15 to 25 times more light than
standard versions, resulting in a signal-to-noise figure improved by the
same ratio.
In some experiments, this improved signal strength is the crucial step
for realizing a measurement at all.
- Flat-field imaging technology
Our instruments are based on high quality aberration-corrected
flat-field gratings. In contrast to conventional gratings these focus
all wavelengths onto a plane rather than a circle. This allows for
positioning the entire detector in the focal plane of the grating for
superior spectral resolution.
- Compactness / Modularity
The spectrometer is very compact and can be bolted directly to a vacuum
chamber. It is capable of carrying its own weight, no table required.
There are no externally moving parts.
Through its modular design, our spectrometer can be adapted to a number
of configurations (source distance, spectral range, detectors, vacuum
pumping, etc). This makes it highly flexible for varying requirements
and experiments.
- Robust against misalignment
The compact design of the spectrometer makes it inherently insensitive
against mechanical and environmental disturbances (vibrations,
acoustics, etc). No externally moving parts and closed-loop grating
actuators with absolute position monitoring add to the robustness and
allow for monitoring of the grating alignment at all times.
In addition, the concept of a spectrometer without entrance slit also
makes the instrument less sensitive to misalignment. Under typical
operating conditions a misalignment of the beam in the dispersion
direction on the entrance of the spectrometer by 500um would lead to a
signal reduction by more than 20% in an instrument with entrance slit
while it is less than 10% for our design.
- Customization
The adaptability of our XUV spectrometer makes it possible to highly
custom-fit the device to requirements. Thus we offer to customize every
spectrometer to exactly match the desired research application. This
includes e.g. interfacing to experimental chambers, adaption of the
source distance, integration of customer-supplied detectors,
user-defined filter mounts, non-magnetic instruments, special mounting
situations, etc.
