GRINM Electro-optic Materials Co., Ltd. (GRIEOM) is specialized in manufacturing sophisticated photoelectric materials. It was formerly known as Beijing Guojing Infrared Optical Technology Co., Ltd.
Germanium crystal, with wide transmission band across 2-14um and relatively high refractive index, is widely used for making lenses and prisms of thermal imaging systems. Grieom produces planar and sphere Germanium blanks, polished parts and optical elements with AR and DLC coating, with the diameter from 8mm to 300mm.
Used as the substrates of infrared and red LED.
GRINM Electro-optic Materials Co., Ltd produces 2-3 inches HB-GaAs monocrystals with high uniformity of electrical resistivity.
GRINM Electro-optic Materials Co., Ltd produces Multispectral ZnS windows with the size up to 600×400×20mm and domes with the size up to φ380×12mm.
CVD ZnSe, fabricated by CVD method, is the best choice of material for use as optical components in high power CO2 lasers due to its ultra low bulk absorption at 10.6 micros. GRIEOM produces CVD ZnSe blanks with the size up to 400×200×15mm.
GRIEOM now provides 4 types of chalcogenide glasses with diameter up to 150mm, products from blanks, polished parts to coating parts.
