Global hyperspectral microscope

IMA is a hyperspectral microscope delivering spectral and spatial information in the VIS, NIR, and SWIR range (400 nm - 1620 nm). This system rapidly maps photoluminescence, electroluminescence, fluorescence, reflectance, and transmittance. Based on high throughput global-imaging filters, IMA is faster and more efficient than standard point-by-point or line-scan based systems.

IMA Applications Overview

  • Perform complex material analyses such as solar cell characterization and semiconductor quality control.
  • Study IR markers in complex environments including live cells and tissue.
  • Retrieve darkfield images and obtain a contrast of transparent and unstained samples such as polymers, crystals or live cells.

Hyperspectral Characterization of Next-Generation Solar Cells and LEDs

This video shows how spectrally and spatially resolved PL and EL maps can help identify defects, losses, and uniformity in advanced materials. A hyperspectral photoluminescence demonstration is performed on large grain perovskite crystals.

Photon etc.’s Global Imaging Technology

This video shows the conceptual difference between hyperspectral global imaging and raster scan (line scan, pushbroom). With global imaging, only a few monochromatic images are required to obtain a hyperspectral cube of data (X-Y spatial, Z spectral). With raster scan technologies, a spectrum needs to be acquired on each point/line within the desired field-of-view.
