Material

OP-Unite can supply a full range of optical glass from Chinese material ,Schott, OHARA to HOYA. OP-Unite is a manufacturer of research and development of optical components made from glass, crystal and plastic materials.

Optical Glass: A noncrystalline, inorganic mixture of various metallic oxides fused by heating with glassifiers such as silica, or boric or phosphoric oxides. Most glasses are transparent in the visible spectrum and up to about 2.5 um in the infrared. We use from Chinese material , Schott, OHARA to HOYA.

Special Glass: Fused Silica, Dynasil fused silica, color glass, float glass etc.

Crystal, A solid with a structure that exhibits a basically symmetrical and geometrical arrangement. Large single crystals often are used because of their transparency in different spectral regions. We can supply: Sapphire, CaF₂, MgF₂, MgO; Quartz, Silicon, Ge, YVO₄, LiNbO₃, KTP etc.

Optical Plastic, is another material we widely used for lens. they serve the purpose of glass optics at a lower cost and a significant savings of weight.
