charged up with photons from the sides and emit a beam of coherent light out of the end--in fact the very first laser was built with a ruby
I don't even know why they were experimenting with this unusual crystal--it has a higher density
which gives it a gorgeous golden yellow color which shifts between different lighting
specifically Bi3Ge4O12 aka evlitine) is valued as an optical substrate because of its highly unusual electrooptical properties
and like Ce:YAG and LuAG it is used as a scintillator to help detect invisible radiation
CutKit™ Index Gears Index:72 Degree charged up with photons fromThese index gears fit the Vevor faceting machine used with the CutKit as well as other similar faceting machines. Each gear comes with a 4mm allen key for installation. Machines usually come with a 96 degree already installed. Index gears are used to set the rotational angle while faceting. The number of teeth on the index gear controls the type of symmetry you can cut into your stone. The default is a 96 degree which allows for most classic cuts but
