We are now manufacturing cathodoluminescence devices for about 15 years starting with the HC1-LM in 1991. However, our experiences with CL techniques can be dated back to the beginning of the eighties - more than 25 years ago.
Precursors:
CL-device by Zinkernagel 1976 at the
Dept. of Geology, Bochum, Germany
CL-device by Neuser 1985 at the Dept.
of Geosciences, Göttingen, Germany
CL microscopes, lumic type:
