Applications of MgO single crystal substrates and optical windows:
- Substrate for high temperature superconducting film formation, such as YBCO film (filter used for communication and space observation)
- Substrate for ferroelectric film formation, such as PZT film (infrared ray sensor used for thermometer and thermoregulator)
- Substrate for diamond growth
- Substrate for magnetic film formation (MRAM, TMR)
- Optical window with anti-reflective (AR) coating - please contact us for a quote
