Aspherical Lenses Definition

Aspheric lens is a lens whose surface profiles are not portions of a sphere or cylinder. In photography, a lens assembly that includes an aspheric element is often called an aspherical lens. As an excellent aspherical lens manufacturer, we bring in hot briquetting technology from Japan, with volume production ability, including aspheric lens which surface form error is within 100 micron.
