Partial dispersion ratios of some new borate and phosphate glasses.
The partial dispersion ratios of phosphate and borate glasses are defined and found significantly different from those of silicate glasses; thus, they are useful for secondary spectrum correction. Refractive index measurement accuracy necessary to ensure significant partial dispersion ratios is analyzed. Measurement techniques and corrections are described.
