普通光学玻璃简介
Classification and Denomination of Colorless 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 a Arab number. We classified them into 18 groups according to their positions on nd - vd situation chart and their main chemical components.
| Name | Code | Name | Code | |
| Flint Crown | FK | Light Flint | QF | |
| Light Crown | QK | Flint | F | |
| Crown | K | Barium | BaF | |
| Phosphate Crown | PK | Dense Barium | ZBaF | |
| Barium Crown | BaK | Dense Flint | ZF | |
| Dense Crown | ZK | Lanthanum Flint | LaF | |
| Lanthanum Crown | LaK | Dense Lanthanum Flint | ZLaF | |
| Spcial Crown | TK | Titanium Flint | TiF | |
| Crown Flint | KF | Special Flint | TF |
From the following chart you can see how our colorless optical glasses are sorted:
We have strong capability to use various optical materials for optical components fabrication, so you can just let us know your applications if you have trouble in selecting proper material, and our engineers can help you select the material correctly.
Most of our raw materials come from the internationally renowned material suppliers, the materials we commonly employed are:
Guangming glass, Schott glass, Ohara glass, Hoya glass, Corning glass
Special glasses: Fused silica, Float glass, Zerodur...
Color glass (see color filter chapter for detail)
Crystal Glass (See Crystal chapter for detail)
The following contents you will learn how our colorless glass are equivalent to Schott, Hoya, or Ohara and some of their characteristic.
