Optical material

Simphoton is capable 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.
To select the right materials seems overwhelming. The simplest way is to let Simphoton know your applications, and we select them for you. Basic optical material datasheet.
