Fluorophosphate optical glass has superior optical performance, low softening point and high fluorescence intensity. Non-aspheric lenses precisely molded with fluoride phosphate optical glass can well eliminate spherical aberration and image aberration of spherical optics, improve image quality and reduce the weight of the optical system. Fluorophosphate optical glass is mainly used in high-precision, high-resolution optical system, such as digital cameras, LCD projectors, LCD projectors and other combination of lenses.
