Featured Spectrometers for 2026
maxLIGHT-pro-XUV Spectrometer
Our maxLIGHT pro offers the high-performance spectrometer functionality of the maxLIGHT combined with a straightforward beam profiler. Automated and quick switching between spectrograph and profiler modes allows for routine verification of beam properties.
The 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.
easyLIGHT-XUV Spectrometer
Our easyLIGHT XUV spectrograph provides aberration-corrected wavelength coverage in the extreme and vacuum ultraviolet spectral region. Based on a normal-incidence geometry, the high-efficiency flat-field grating provides wide-band spectral measurements covering 30 to 200nm. The spectrometer can be used without entrance slit to maximize light collection for a range of source distances.
easyLIGHT VUV Spectrometer
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).
X-Ray Absorbance Spectroscopy (XAS)
Our product portfolio includes integrated XAS systems both for near and extended energy regions of an absorption edge.The NEXAFS region close to the absorption edge shows the largest variations in the x-ray absorption coefficient and is often dominated by intense, narrow resonances caused by the transition of core electrons to non-bound levels. NEXAFS is sensitive to local atomic states such as oxidation states.
