S-NBH58 is an optical glass with low partial dispersion ratio θg,F and can be effective for correcting chromatic aberrations when combined with anomalous dispersion glass types with both low refractive indices and low dispersion. S-NBH58 is recommended for polished lens blank applications and can be very effective for use in higher performance products, such as Interchangeable Photographic lenses, Projectors, and various others.
