Cyberstar MF3000 is a high temperature Xenom Lamp based optical vertical floating zone furnace, offered by ECM Greentech, to growth garnet single crystal size up to Ø5mm, length 30mm, at up to 3000°C. Heating energy is obtained by focusing light on a small area of the processed rod using high efficiency reflective and concentrating mirrors. The furnace operates based on the floating zone technique using one rod of the grown material, or a seed and feeding rod to provide the melted drop. Both of these solutions are possible thanks to the independent vertical conversion between the upper and lower holders in the furnace. The movement of the upper and lower rods is perfectly synchronized using the Cyberstar control software, which is included with the furnace. It can be used to obtain crystal rods or crystal fibers, at pressure up to 10 or 100 bar by using related dedicated chamber. The specific design of the furnace makes it ideal for laboratory use, universities, and R&D centers.
