YYGJ is committed to the R&D and manufacturing of infrared window materials. The company's main products include germanium crystals, standard&multispectral zinc sulfide, sulfur based glass, and a series of popular infrared products,.
The product is widely used in various fields such as infrared thermal imaging, ocean/ship, aviation/aerospace, security/national defense, optical materials and components, monitoring equipment, etc.
Germanium crystal
The transmission band of germanium crystals covers 2-14 μ The infrared band has a high refractive index and is mainly used for optical components such as lenses and prisms in thermal imaging systems.
YYGJ can provide single crystal germanium, polycrystalline germanium flat and spherical blanks with a diameter of 5mm~3500mm, polished parts, as well as products coated with AR anti reflective film and DLC protective film.
Application field:
Infrared products, ocean/ship, aviation/aerospace, security/defense, optical materials and components
Standard & Multispectral CVD ZNS Zinc Sulfide
YYGJ uses a self-developed chemical vapor deposition process to prepare standard ZnS polycrystalline materials. Multi spectral ZnS is obtained from standard ZnS after hot isostatic pressing treatment.
Multispectral ZnS exhibits excellent optical transmission performance in the full wavelength range from visible light to long wave infrared, meeting the needs of advanced applications such as laser infrared composite windows and visible light laser infrared "three light in one" windows.
It has achieved theoretical density and excellent uniformity, and has excellent optical transmission performance in the long wave infrared band (8-12um), as well as good mechanical strength and environmental stability. It is the preferred material for long wave infrared windows and headsets.
Element level ZnS:
Transmittance band width (2.5-12 μ m) Outstanding advantages such as high high-temperature infrared transmittance and good thermal shock resistance, which applied to scenarios of high temperature exceeding 400 ℃.
Size:300mm×400mm
Chalcogenide glass
Sulfur based glass is a special infrared glass material with a wide transmission band range, excellent optical properties, and wide applications.
It has stable chemical properties, strong acid resistance, and can eliminate color differences in infrared optical systems. It is an ideal infrared lens material and the preferred material for precision molding of infrared lenses.
YYGJ has developed six grades of sulfur based glass, with a maximum diameter of 150mm. It can provide different product forms such as blanks, polished parts, and coated parts.
