XUV/VUV Spectrometers

easyLight maxLIGHT Spec. Summary

Our easyLIGHT spectrograph provides aberration-corrected wavelength coverage in the vacuum ultraviolet spectral region. Based on a normal-incidence geometry, it offers spectrograph and monochromator functionality. The high-efficiency gratings can be rotated about their apexes by a high-accuracy positioning system, resulting in a wavelength selection accuracy at the exit slit of <0.1 nm. Entrance and exit slit widths can be set in the range of 0.01 to 4 mm by micrometer screws or a motorized actuator (optional).

Versatility

• Spectrograph and monochromator in one device

• Slits continuously adjustable manually or motorized (optional)

• Compact and cost-effective

Special Solutions

• Non-magnetic instruments

• UHV configurations

• etc

Efficiency and Accuracy

• High accuracy wavelength selection by closed-loop micro-precision

grating actuator

• Grating positioning controllable by software

• Highly efficient aberration-corrected grating

• Double stray light filter

Customization

• Every spectrometer is customized to exactly match the desired

application, e.g:

• Interfacing to experimental chambers

• Adaption of the source distance

• Integration of customer-supplied detectors

• User-defined filter mounts

Our maxLIGHT spectrograph 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.

Direct Imaging of the Source

• Images the source directly onto the detctor, does not require a narrow

entrance aperture

• ~20 times more light collection 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

Rugged and Robost Design

• Compact design, small footprint

• Inherently insensitive against environmental disturbances and

misalignment due to omission of entrance slit

• No moving parts

• Absolute grating position monitoring for maintaining grating alignment

• Can be bolted directly to a vacuum chamber

Special Solutions

• Non-magnetic instruments

• Special housing geometries, in-chamber solutions

• EMP-protection

• UHV configurations

Customization

• Every spectrometer is customized to exactly match the desired

application,

• Interfacing to experimental chambers

• Adaption of the source distance

• Integration of customer-supplied detectors

• User-defined filter mounts
