Aspheric lens is an optical element which have a complex radius of curve, at least one surface is not spherical. The radius of curve is gradually change from center to edge, there have a specified formular of aspheric lens which designed by customers. Compare with spherical lens, aspheric lens reduces or minimizes spherical aberrations, for example, astigmatism, field curvature, and distortion.

Optical glass lenses are precision components made from specially formulated glass designed to optimize light transmission and minimize distortion across various wavelengths. These lenses are essential in various applications, including cameras, microscopes, telescopes, and medical imaging devices. They are engineered to achieve high levels of clarity and focus, enhancing the performance of optical systems.
