• Spectrograph and monochromator functions
• Gratings with optimal efficiency
• Wavelength range from 1 to 200 nm
• High-precision wavelength setting
• Compact, modular design

Thanks to its seamless design, the maxLIGHT pro offers the largest light collection and highest efficiency in its class of spectrometers. The aberration-corrected flat-field wavelength range covers a broad spectral bandwidth from 1 nm to 200 nm; for example, a single grating can cover 5-80 nm.

Its modular design can match different experimental configurations. It features an integrated slit holder and filter insertion unit, as well as motorized grating positioning.

Flexible and comprehensive detector configuration options

nXUV CCD — for high-resolution, high-dynamic-range applications

MCP/CMOS — for wide spectral range, gated, or image-intensified detection requirements, customizable according to user needs

Slitless design

HPS's proprietary spectrometer design uses direct source imaging technology. Therefore, no narrow entrance slit is required, and the collection of incident light is maximized. Compared with traditional spectrometer architectures, the light intensity reaching the detector is more than 20 times higher. This structure also greatly improves the stability of daily operation.

Measurement results

	Characterization of HHG via maxLIGHT XUV (left) in coincidence spectroscopy applications using attosecond XUV pulses. High-order harmonics originate from single-photon transitions (blue arrows), while two-photon transitions of XUV and IR light appear as sidebands in the photoelectron spectrum (right). J.

	At the same signal intensity, the maxLIGHT pro spectrometer (solid line) provides significantly higher resolution than a standard spectrometer (dashed line). To achieve equivalent spectral resolution, conventional spectrometer technology requires narrow slits, which significantly reduces signal intensity. C.

	HHG spectrum in the cutoff region at 150 kHz repetition rate obtained with maxLIGHT XUV. Changes in CEP reveal that intensity modulation begins to disappear at certain CEP settings, indicating the presence of isolated attosecond pulses. M.
