S-NBH58

Though S-NBH58 has high refractive indices with high dispersion, the partial dispersion ratio θg,F is low. That's why S-NBH58 could be effective for correcting chromatic aberration by combining it with anomalous dispersion glasses having both low refractive indices and low dispersion. We are pleased to introduce S-NBH58 which could be effective for higher performance of customer's products and could be used for various applications such as the lenses of Interchangeable lens cameras, Projectors and so on.
