Material:

Sinoceramics has the capability to fabricate optical components with various optical materials. Some of the most important material properties to consider for optical elements are:

  • Transmission versus wavelength
  • Index of refraction
  • Thermal characteristics
  • Mechanical and chemical characteristics
  • 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 below is intended to assist in these situations. It is very important to select the best material for your optical component(s).
