Diamond Exploratory & Applied Research MPCVD
Versatile CVD Diamond Research at an Affordable Price
The Blue Wave DEAR MPCVD system is designed for CVD diamond researchers working in electronics and quantum photonics. Its defining feature is a replaceable quartz tube reaction chamber — allowing researchers to use the same system across a variety of dopants without cross-contamination.
The system supports synthesis of CVD diamond in epitaxial, single crystal, polycrystalline, microcrystalline, and nanocrystalline forms — doped and undoped — with growth rates from 0.1 to 3 μm/hr.
