S-LAH99 is an optical glass with higher transmission, decreased specific gravity, lower cost, and is located in a similar optical region as S-LAH79.

This new material can be used for a variety of uses such as Interchangeable Photographic lenses, Projectors, and various other applications. We’re excited to introduce S-LAH99 as an effective option for both cost reduction and higher performance.
