Leucosapphire monocrystal growing machine (per Kyropoulous method)
- Microelectronics
- Optoelectronics
- LEDs, medicine
- R-axis, A-axis configuration
- 2,4,5,6,8-inch cylinders
- Optimized cylinder cutting program
- High crystal growth rate – 83 kg boule - in 15 days
We have achieved 55% of using of 83 kg of boule for cutting suitable blanks of 2 ”and 6” inch cylinders.
Total length for 2 ”blanks 5345 mm.
The annual total gross output of 2 ”cylinders (TIE) can reach 100,000 mm).
