Type Code nc nd nF ng vd s.g. Coloring
S-LAH66N 773496 1.76779 1.77236 1.78338 1.79199 49.55 4.23 (370)/305

S-LAH66N has been modified in dispersion properties compared to conventional glass to meet the demands for high-precision lenses. Adjustments have been made to the refractive index (excluding d-line), partial dispersion, partial dispersion ratio, abnormal dispersion, and the constants in the dispersion formula to reflect the changes in dispersion characteristics. Other properties remain unchanged.

S-TIH53WN and S-LAL18N have also been modified for the demands of high precision lenses.
