By directly creating lens shapes from molten glass droplets, we provide shapes and quality that cannot be achieved with conventional glass molds!
Utilizing the high degree of freedom in the shape of the glass droplet receiving surface, which is a feature of Konica Minolta's unique droplet glass mold technology, it is possible to manufacture glass lenses (commonly known as seagull lenses) with inflection points on both sides, which are difficult to mold using conventional re-heating methods. This lens has become an essential shape for low-profile cameras, and by manufacturing it from glass, an all-glass lens module for ultra-low-profile cameras that is resistant to temperature changes can be realized. Examples of achievements: - Outer diameter size: up to φ9mm - Inter-surface eccentricity precision: less than 5μm (precision), 7.5μm (general purpose). - Center thickness precision: ±0.005mm (precision) and ±0.01mm (general purpose) for outer diameter sizes up to φ5mm. - Surface roughness (PV): less than 0.3μm (precision) and 0.9μm (general purpose) for outer diameter sizes up to φ5mm, and less than 0.4μm (precision) and below 1μm (general purpose) for sizes from φ5 to φ9mm.
