We introduce our new glass S-FPM5, with dn/dT closer to zero than other Fluor-Phosphate-types, for correction of index temperature-drift. In addition, it has a high partial dispersion ratio θg, F, which is a characteristic of Fluor-Phosphate based glass materials and is effective for correcting secondary chromatic aberration. This glass material can be used, not only for in-vehicle camera lenses, but also for other applications such as projector and interchangeable lenses.
The annual review of our product range with regard to worldwide usage involves grading the following glass types, from Recommended to Special-Order-Glass-Type.

S-LAL21 has improved on chemical durability, that's why it could be used for Automotive camera lenses, as well as projectors, photographic interchangeable lenses and various applications.
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.
S-NPH7 is an optical glass which has the smallest dn/dT in the region of NPH, high refractive indices and high dispersion.

Cars are used in environments where the temperature change is large from below zero (in cold district) to 50 ° C or above (inside car in summer). When we make the design of optical system, considering refractive index fluctuations due to temperature change should be needed. Generally speaking, NPH glasses have positive dn/dT and the value of dn/dT is large at the positive side....
