New Glass Types


S-LAH95 is an optical glass recommended for polished lens blank applications located in the high refractive index and low dispersion region. By reducing usage of expensive raw materials, S-LAH95 provides significant cost reduction. This is the fourth glass that has been developed in the same concept as S-LAH89, S-LAH92 and S-LAH93 that have been already released. We are pleased to introduce S-LAH95 optical glass with these unique properties to provide advantages in technical design and decreased production costs.
