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.
