Confocal controlled LIBS microscopy with high spatial resolution and stability

Abstract

A novel confocal laser-induced breakdown spectroscopy (CLIBS) microscopy, is proposed to improve the spatial resolution and stability of LIBS-based imaging. CLIBS uses the light reflected from the sample illuminated by...

Atomic spectrometry update: review of advances in atomic spectrometry and related techniques

“…3D elemental maps with high spatial resolution were obtained by Huang et al 130 using a novel confocal controlled (CC) LIBS microscope. This technology provided a lateral resolution of about 700 nm for morphological imaging and about 10 μm for elemental mapping.…”

A confocal-controlled Raman-LIBS hybrid microscope with high stability and spatial resolution

“…33 Recently, a similar strategy has been applied to the LIBS, which signicantly enhances the signal-to-noise ratio during the long-term measurement. 34,35 In this paper, we propose a confocal microscopy-controlled Raman-LIBS hybrid method with high spatial resolution and stability. The confocal system, depending on the Rayleigh/ reected light, is described as confocal controlled microscopy, which measures surface topography and achieves highprecision axial focusing, enabling long-time threedimensional (3D) spectral mapping of the sample.…”
