PRODUCT > Optical Glass Database > Optical Glass Types

Optical Glass Types

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 (Table 1).

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 glass type designation, a six-digit code is listed in this catalogue. The first three digits indicate the three numbers after the decimal point of the glass refractive index and the last three digits indicate the Abbe-number. For example H-K9L, nd=1.51680, vd=64.2, its code comes to be 517642.

Designation of the Optical Glass without Lead, Arsenic and Cadmium

The optical glass without Lead, Arsenic, Cadmium and other radioactive elements is expressed by a prefix 'H-' indicating its eco-friendly characteristics, for example: H-K9L.

Designation of Low Softening Point Glass Types

Low softening point glass type without Lead, Arsenic, Cadmium and other radioactive elements is prefixed by an alphabet 'D-', for example: D-K9L.

Designation of UV High Transmittance Glass Types

The type of UV high transmittance is prefixed by an alphabet 'U' as usual, which means ultraviolet, for example UQF50. High transmittance glass type is expressed by a suffix '-HT' meaning high transmittance, for example ZF7LHT.
