Quality Inspection for Silica Window - GSGG Crystals – Dien

GGG/SGGG/NGG Garnets are used for liquid epitaxy.SGGG subatrates is dedicated substrates for magneto-optical film.In the optical communication devices,require a lot of using 1.3u and 1.5u optical isolator,it’s core component is YIG or BIG film been placed in a magnetic field.
SGGG substrate is excellent for growing bismuth-substituted iron garnet epitaxial films,is good material for YIG,BiYIG,GdBIG.
It’s good physical and mechanical properties and chemical stability.
Applications:
YIG,BIG epitaxy film;
Microwave devices;
Substitute GGG
