Classification of Optical Glass Types
CDGM Optical glass can be classified into 17 groups according to its different refractive index (Nd) and dispersion coefficient (vd) POSITIONS IN THE Nd-Vd diagram and their chemical composition.
Group | CDGM | Group | CDGM |
Fluorine Crown | FK | Light Flint | QF |
Light Crown | QK | Flint | F |
Crown | K | Barium Flint | BaF |
Phosphate Crown | PK | Dense Barium Flint | ZBaF |
Dense Phosphate Crown | ZPK | Dense Flint | ZF |
Barium Crown | BaK | Lanthanum Flint | LaF |
Dense Crown | ZK | Dense Lanthanum Flint | ZLaF |
Lanthanum Crown | Lak | Special Flint | TH |
Crown Flint | KF |
Designation of Optical Glass Types
Each optical glass type within a group is designated by an abbreviated group symbol and a number. In addition to the optical glass manufacturer has their type designation, Most optical glass manufacturer has a code number, which is a six-digital code is listed in this catalogue. The first three digitals indicate the three numbers after the decimal point of the glass refractive index and the last three digitals indicate the Abbe-number, for example:
H-K9L nd=1.51680, Vd = 64.20, Its code comes to be “517642”
N-BK7 nd=1.51680, Vd= 64.17, Its code comes to be “517642”
S-BSL7 nd=1.516330, Vd= 64.14, Its code comes to be “516641”
Index Catalog
In this mutual Index table, the equality of glass type refers to the simial code of glass, but the glass composition is different among that of CDGM, HOYA, OHARA and SCHOTT.
CLZ Optics collected third-party product data, we makes every effort to verify, but accepts no pesponsibility for accuracy. These data collection date is January 2021, for accurate technical data, please check with CDGM, HOYA, OHARA and SCHOTT.
