The processing level of optical spherical lenses can reach ISO3290 standard level 3, with a diameter range of 0.3-250mm and a diameter tolerance of+/-0.001mm. It is mainly used in fields such as laser, optical communication, infrared applications, medical imaging, and photovoltaic industry. We produce optical communication credit spherical lenses, sapphire spherical lenses, zinc selenide spherical lenses, K-lenses, calcium fluoride, germanium silicate glass, zinc selenide, and infrared glass lenses, with quality far exceeding the technological level of Japan and Germany. We mainly import optical credit glass ball lens materials produced in Germany and Japan.
