Special dispersion fluorophosphate optical glass

Currently, there are about 200 kinds of colorless optical glass at the Company, including special dispersion fluorophosphate optical glass, ultra-high refractive index optical glass, high transmittance optical glass, and low melting point optical gl

Product information

Special dispersion fluorophosphate optical glass has a large Abbe number, high transmittance, negative refractive index temperature coefficient, and high special relative partial dispersion value. It can effectively eliminate secondary spectra in optical system design, and has a low softening temperature. It can be used for precision molding, optimization of optical structure, reduction of optical system volume and weight。
