Optical Material

TEMTO has the capability of fabricating a wide variety of optical components with various optical materials. The most important material properties to consider for an optical element are transmission versus wavelength, index of refraction, thermal characteristics, mechanical and chemical characteristics and cost.

There are two instances in which you might need to know more about optical materials. First, you may need to determine the performance of a catalog component in a particular application. Second, you may need specific information when selecting the material for a custom component. The data in the following is intended to assist in these situations.

To select the right materials seems overwhelming. The simplest way is to let us know your application,and we can select themfor you.

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, Calcite, MgF2, MgO, Quartz, Silicon, Ge, YVO4, LiNbO3, KTP etc.

Optical Plastic: 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.
