Global Hyperspectral Raman Microscope
RIMA is a hyperspectral global microscope delivering spectral and spatial information. This system rapidly provides Raman maps over large megapixel-scale fields of view. Based on high throughput global-imaging filters, RIMA is faster and more efficient than standard point-by-point or line-scan-based systems.

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.
