Dark-field scattering nanoparticle detection
Dark-field microscopy is a special microscopic technique realized under dark-field illumination, which prevents light unrelated to the object under observation from entering the objective lens and presents a clear outline of the object against a dark background. Microparticles as small as 4-200 nm can be visualized with a resolution up to 50 times higher than that of normal bright-field illumination microscopy. Microscopes equipped with hyperspectral imaging systems can be used to identify the types of particles.
The figure shows VNIR hyperspectral imaging of lung tissues from mice after a single intratracheal drop of low (18 pg) and high (162 pg) titanium dioxide nanoparticles to determine the location of particle retention in these tissues.

OLED display luminescence test
The microscopic hyperspectral imaging system can obtain the light-emitting images of OLED display with higher spatial resolution through different magnification eyepieces, and detect the uniformity and stability of OLED display light-emitting through the feature of "one spectrum in one" of hyperspectral image data.

Wafer material and defect detection
Non-contact, non-destructive, fast and accurate micro-region measurement technology, which can be operated at room temperature or on-line in production, can obtain the PL Mapping of the entire wafer, thus obtaining important information about the group distribution ratio of the substrate or epitaxial layer, defects and other properties of the material in the micro-region of the homogeneity. Based on the micro-hyperspectral imaging technology, the material of the wafer and the change of the concentration of the luminescence center of the sample can be identified on a fine scale.

Applications in Chalcogenide Crystals
The micro-hyperspectral imaging system for detecting inhomogeneities in chalcogenides has the following advantages over traditional techniques such as confocal microimaging: single whole-field-of-view imaging; the intensity of the excitation source in the field of view of the system is uniformly distributed in PL imaging experiments; and quantitative values of spectral intensities can be obtained.
