Hontec optics has strong capability in fabricating 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. Many glass manufacturers offer the same ma- terial characteristics under different trade names. Based on availability, we reserve the right to substitute an equivalent glass in our production runs.
The materials that Hontec optics has ever used include:
Colorless Optical Glass: Guangming, Schott , Hoya , Ohara .
Special Glass: Fused silica, Colored glass, Pyrex,D263,BoroFloat, B270, …
Optical Crystal: Si, Ge ,CaF2, MgF2, ZnSe ,Quartz, Sapphire, … ,
Colored Glass: ZJB300,JB400,CB550,HB610,HWB780,QG21,LB12 …
Colorless Optical Glass
Our optical glasses are classified by their main chemical components and are identified by refractive index (nd) and Abbe-number (Vd). Primarily they can be divided into groups, and further they can be identified into various types. Each group has a name and a code, and each type of glass within some group is named by the abbreviated group symbol and an Arab number. We classified them into 18 groups according to their positions on nd- Vd situation chart and their main chemical components.
