NHG has developed a new type of fluorphosphate glass product H-FK95 with independent intellectual property after mass production of H-FK61, H-FK69, making the series of fluorphosphate glass products more various.

NHG’s H-FK95 has the index (n_d) of 1.43700, Abbe-number (υ_d) of 95.10. It has the lowest dispersion and the highest Abbe-number in optical glass field, belonging to fluorphosphate glass materials of low dispersion. Moreover, this glass has very high abnormal dispersion, showing excellent achromatic performance in optical design. It can also simplify, optimize optical imaging system and improve imaging quality.
