Optics Materials
Co-Energy has capability in manufacturing various optical components with a wide variety of optical materials.Selecting an optical material is important since each material has different optical characteristics,such as transmission versus wavelength,index of refracton,thermal,mechanical and chemical characteristics.
The index of refraction and Abbe Number of a glass are typically used by designers as degrees of freedom when designing systems. Foctek has a program that combines the foundation data of a wide variety of optical materials. It is easy for us to find the right materials for your online_ordering.
