Optical lenses made by spherical lens manufacturers (I)
Optical lenses made by spherical lens manufacturers are one of the indispensable important products for scientific and technological development
Optical glass made by spherical lens manufacturers refers to the glass that can change the propagation direction of light and the relative spectral distribution of ultraviolet, visible or infrared light. Optical glass is defined as a glass with uniform optical properties and specific requirements for refractive index, dispersion, transmittance, spectral transmittance, light absorption and other optical properties. The optical glass is mixed with high-purity silicon, boron, sodium, potassium, zinc, lead, magnesium, calcium, barium and other oxides according to a specific formula, melted in a platinum crucible at high temperature, stirred evenly with ultrasonic wave, and removed of bubbles; Then slowly cool down for a long time to avoid internal stress of glass block. The cooled glass blocks must be measured by optical instruments to check whether the purity, transparency, uniformity, refractive index and dispersion index meet the specifications. The qualified glass blocks are heated and forged to form optical lens embryos.
