Slit-less Technology in Spectrometer

Direct imaging of the source

In contrast to conventional devices the innovative XUV / VUV spectrometers by HP do not require a narrow

entrance aperture but rather image the harmonic source directly onto the detector. Thus 80% or more of the

incoming beam can be used for measurement. 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.

Superior signal strength

The amount of light collected by the spectrometer is the key factor influencing its overall sensitivity and ultimately the most important feature required to obtain high

quality data even from weak sources. Conventional spectrometers use an entrance aperture (slit) at a fixed distance from the grating to create a small source which

is then dispersed and imaged onto the detector. In contrast to that the H+P spectrographs can be configured to directly image a radiation source positioned at any

distance from the grating onto the detector. In practice this allows for the collection of 15 to 25 times as much light from point-like radiation sources compared to a

conventional spectrometer with a 100µm entrance slit without degradation in spectral resolution.

Rugged design

The compact design of our XUV and VUV spectrometers makes them inherently insensitive against mechanical and environmental disturbances (vibrations, acoustics,

etc). No moving parts on the outside and closed-loop motors with absolute position monitoring inside the instrument add to the robustness and allow for monitoring of

the grating alignment at all times. The spectrometer can be bolted directly to a vacuum chamber and is capable of carrying its own weight. No table required. The

design also allows mounting in virtually any orientation.

Robust against misalignment

Owing to the rugged design even smaller bumps do not influence the instruments alignment. If the instrument is knocked heavily while the motor control is enabled, the

grating can be repositioned to the saved setting using the grating positioning motors. 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.

Flat-field imaging technology

All our spectrometers 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.

maxLIGHT pro

NO-SLIT FLAT-FIELD XUV SPECTROMETER AND BEAM PROFILER

Our maxLIGHT spectrometer features aberration-corrected flat-field wavelength coverage from 1nm to 200nm.

Wide-band spectral measurements are possible by three gratings covering 1-20nm, 5-80nm, and 40-200nm.

The spectrometer can be used without entrance slit to maximize light collection for a range of source distances.

Its modular design is able to match different experimental geometries and configurations. It features an

integrated slit holder and filter insertion unit, as well as a motorized grating positioning.

Sample measurement demonstrating the improved signal strength.

With the same signal strength, the resolution of maxLIGHT (solid

lines) is significantly higher compared with a standard spectrometer

(dotted lines). For equivalent resolution, standard technology would

require a narrow slit setting and thus a significant degradation in

signal strength. The proprietary no-slit technology delivers high

resolution and signal strength at the same time.(data courtesy of
