Optical lenses are meticulously crafted using a precise formula combining high-purity silicon, boron, sodium, potassium, zinc, lead, magnesium, calcium, and barium oxides. These materials are melted at high temperatures in a platinum crucible and uniformly stirred using ultrasonic technology to eliminate bubbles. This process ensures the creation of high-purity optical lenses with superior transparency and consistency.

After slow cooling to minimize internal stress, each lens undergoes rigorous testing using advanced optical instruments. These tests verify the purity, uniformity, refractive index, and dispersion rate, ensuring our lenses meet the specifications required for precision optical components.
