Aspheric lenses are used to eliminate spherical aberration in a range of applications, including barcode scanners, laser diode collimation, or OEM and R&D integration.
The biggest advantage of aspheric lenses is that they can eliminate spherical chromatic aberration, improve the accuracy of focusing, and have a simple structure. Aspheric lenses can be used to replace multiple lens systems, thereby reducing weight, volume, and cost. One characteristic of aspheric lenses is that its surface is neither spherical nor cylindrical. Aspheric lenses have different radii of curvature from the center to the edge of the surface, so aspheric lenses can eliminate spherical aberration and errors that other spherical lenses cannot eliminate.
We create all kinds of custom aspheric lenses for customers.
