An aspheric lens is a lens whose surfaces profile is neither a portion of a sphere nor of a circular cylinder. Since it is not spherical, the conventional production processes no longer apply to making aspheric surfaces. The production of such elements requires a high-end level of production expertise and technology. The main advantage of aspherical lenses is that they can better correct optical aberrations compared to spherical lenses. Only one aspherical lens is needed for the correction of optical defects, often times with even better results than a combination of more spherical lenses. This technological approach results in smaller diameters, a smaller number of optical elements, and lighter weights of final systems – which is critical to many of our customers’ applications.
At Clear Align, we manufacture aspherical lenses with high surface quality and accuracy and we understand the importance of balancing cost and performance for less demanding applications that still require precision and well controlled manufacturing. That is why our extensive experience in optics includes aspherical lenses in a broad range of shapes, materials, focal lengths and diameters, with different quality levels to address the various performance requirements of our customers. Clear Align has the knowledge to understand your need, quickly design a customized aspheric lens, and supply the best component for your application.
