Even without formal drawings, please provide size, shape, glass type, and quantity. We welcome consultations from the conceptual stage.

What is an Aspherical Lens?

An aspherical lens features a non-spherical surface profile designed to reduce optical aberrations. A single aspherical element can replace multiple spherical lenses, enabling more compact, lightweight optical systems while maintaining sharp image quality across the entire field.

Mold Pressing Technology

Glass aspherical lenses are manufactured using a precision mold pressing process. Preformed glass is placed into an aspherical mold, heated, and shaped under controlled pressure to achieve high surface accuracy.

Production Process

A continuous molding system enables controlled heating, pressing, and cooling, supporting efficient and stable mass production.

Quality Assurance

Strict quality control processes are implemented throughout production to ensure consistent performance. Dimensional accuracy is controlled at the micron level using advanced measurement systems. We utilize UA3P ultra-high-precision 3D surface measurement systems.
