Correlative Imaging of 2D Material Heterostructures: Raman, Photoluminescence (PL) and Second Harmonic Generation (SHG)
This application note highlights the capabilities of the witec360 platform for correlative studies of two-dimensional (2D) materials. It explains how combining Raman microscopy with techniques such as photoluminescence and polarization-dependent second-harmonic generation (SHG) can provide detailed...

Enabling TRISO Metrology Using Mueller Matrix Imaging
This paper demonstrates how Mueller Matrix Imaging (MMI) enables fast, precise evaluation of TRISO fuel particle coatings. By comparing traditional Two-Modulator Generalized Ellipsometry (2MGEM) with the high-speed MMI system, it shows how polarization imaging rapidly detects coating defects,...

Designing a Custom Fluorescence LED Illumination System
Automated imaging is transforming life science research, clinical diagnostics, and even industrial inspection - but not all components of an imaging system are equal. The light source may seem simple, yet it often defines system performance. This paper reveals why high-performance LED illumination...
