Lambda Microscopic Hyperspectral Imaging Systems Lambda-VNS
Lambda microscopic hyperspectral imaging fits most commercial microscopes. An area detector, drive supply, motion control and acquisition modules are integrated without a motorized stage, greatly reducing size/weight for simple microscope operation. Applications include tumor-cell identification, hemorrhagic-polyps/fleshy-white-patch identification, lymphocytic-leukemia screening, cytoplasm/nucleus discrimination and cell counting. Darkfield excludes unrelated light from the objective, revealing clear outlines on a dark background; particles as small as 4~200nm can be seen, with resolution stated as 50 times ordinary brightfield. Hyperspectral microscopy identifies particle types. The figure uses VNIR imaging of mouse lung after a single low (18 pg) or high (162 pg) intratracheal titanium-dioxide nanoparticle dose to locate retained particles. Darkfield hyperspectral images show white-inclusion aggregates in the middle image; hyperspectral maps show red dots/aggregates below. Different eyepiece magnifications produce high-spatial-resolution OLED emission images, combining images/spectra to inspect uniformity/stability. Noncontact, nondamaging, rapid microregion measurement operates at room temperature or inline, obtaining whole-wafer PL Mapping for substrate/epilayer composition ratios, defects and other microregional uniformity. It identifies wafer materials and changes in emission-center concentration at fine scales. Compared with confocal imaging for perovskite inhomogeneity, advantages include single full-field imaging, uniform excitation intensity across the PL field and quantitative spectral intensity. Semiconductor uses include emission uniformity, defect analysis and spatial LED-chip temperature distributions. Additional cases from readable page text: rapid hyperspectral identification of laryngeal mucosal hemorrhagic polyps/fleshy-white-patch regions, shown red; tumor/abnormal-cell spread at 20-times eyepiece magnification; rapid nucleus/cytoplasm/other-material discrimination; counting by cell centroids, total 402; darkfield nanoparticle-exposed tissue, upper image; OLED emission at 20X,50X,100X; images/spectra of boron-implanted, aluminum-implanted and special unimplanted wafers; perovskite PL data: (a)/(b) are monochromatic images at 625nm/750nm, (c) spectra from different positions in Figure 1, (d) regional PL spectral-shift imaging; hyperspectral inversion of temperatures on different LED source panels.

Electro-optic deflectors (EODs) are optical devices used to steer or deflect light beams by applying an electric field to a specialized optical crystal. Unlike mechanical beam steering systems that rely on moving mirrors, electro-optic deflectors enable high-speed, non-mechanical beam control with exceptional precision and responsiveness. They are widely used in laser scanning, optical communications, microscopy, laser printing, spectroscopy, and scientific research, where rapid and accurate laser beam positioning is essential.
