This page lists the manufacturer glass catalogs that have been incorporated into the built-in glass library in LensForge. Manufacturers wishing to have their catalogs added to the built-in library for future releases need only provide their data in a format conducive to automated input.
The glass library also contains data on some plastic materials.
The date code used in the catalog name (glass version) is either the catalog date given by the manufacturer or the file modification date of the catalog downloaded from the manufacturer's web site. The date is in the standard international format of ISO 8601.
Glass name alone is not enough to distinguish between dissimilar glasses. For example, LAKN12 from Sumita has code 734512, whereas LAKN12 from Schott has code 678552. The corresponding refractive indices 1.734 and 1.678 are quite different.

In the raw catalog seven dispersion coefficients for the Schott formula are given, with the last coefficient zero except for one glass (E-LAKH1). For the time being, this last coefficient is ignored by LensForge, as by ZEMAX and GlassBank.

In raw catalog the glass code contains hyphen. E.g., 649-530. Hyphen is removed in LensForge catalog so that glass codes sort amongst those of other vendors.

Glass code contains fractional part. E.g., 527662.283. Code is a string in LensForge so this is OK.

Glass type can contain lower case letters. E.g., K-PSKn2. LensForge accomodates this, but sorts and searches in a case-insensitive manner.
