01 · Overview
One platform, four measurement modes
The modular RTS2-Omni-Imager moves beyond single-technique spectrometers. It records image and spectral information together for fast, in-situ, correlative analysis of physical, chemical, and biological processes at the nanoscale.
Push-broom hyperspectral imaging
Capture a complete data cube in roughly 10 seconds to one minute, depending on camera settings, without point-by-point scanning.
Patented focal-plane scanning
An internal precision motorized stage handles acquisition, focus, and depth-of-field adjustment through Zolix focal-plane scanning technology.
Large-area automated mapping
An optional motorized XY stage maps large samples and automatically stitches and corrects each swath into a seamless image.
Depth-resolved imaging
Motorized autofocus supports in-situ imaging across sample layers for large-area, multi-dimensional, and tomographic measurements.
02 · Technology
Dark-field microscopy meets hyperspectral imaging
Dark-field microscopy
A dedicated illumination and observation geometry directs only sample-scattered light into the objective. Small particles, fibres, and interfaces stand out against a dark background, including structures below the conventional bright-field diffraction contrast limit.
Hyperspectral imaging
Tens to hundreds of continuous narrow spectral bands create a complete spectrum for every image point. A push-broom imaging spectrometer records one spatial line at a time, combining spatial and spectral axes into a calibrated three-dimensional data cube.


03 · System configuration
A modular optical architecture
A dark-field microscope, imaging spectrograph, hyperspectral camera, and high-sensitivity detector form the core. Optional laser and confocal paths add fluorescence and Raman excitation while keeping conventional spectrograph access available.



04 · Software & database
Modular spectral-image processing
Image-processing and spectral-identification modules cover classification, spectral-angle matching, linear unmixing, divergence analysis, band math, PCA, calibration, retrieval, and spectral-database management.
Band extraction and frame selection
Select the wavelength range and channel count of interest, increasing acquisition speed when fewer bands are required.
Calibration and retrieval
One-click reflectance calibration, batch processing, binning, cropping, format conversion, and model-based real-time retrieval.










05 · Applications & measured data
From single nanoparticles to perovskite films
Correlative image and spectrum acquisition supports dark-field scattering, nanomaterials research, life sciences, camouflage detection, and pharmaceutical or medical analysis.
