What is Hyperspectral Cathodoluminescence ?

At Attolight, we define Hyperspectral Cathodoluminescence (CL) by the capacity of generating images with 1600 channels – or colors – per pixel. With each channel occupying 16 bits of memory, a single 1024 by 1024 pixel map represents a total of 3.4 gigabytes of data. Our technology provides millisecond hyperspectral CL maps with an acquisition time of one millisecond per pixel thanks to a high collection efficiency (NA=0.72), guaranteed zero photon-loss on apertures over a field of view of 300 µm, optimized control of the entire microscope – from the scanning coils to the camera –, and a very robust software solution capable of handling the huge data acquisition rate without stuttering.
