Aspherical lenses are used in a range of applications, including barcode scanners, laser diode collimation, and integration for OEM and research and development, to eliminate spherical aberration. The use of aspherical lenses in single lens designs helps minimize the number of lenses in optical assemblies composed of multiple lenses. Unlike conventional lenses that adopt a spherical shape on the first surface, aspherical lenses feature a more complex surface shape where the curvature gradually changes from the center to the edge of the lens. Reducing the total number of lenses contributes not only to a decrease in the size and weight of the system but also simplifies the assembly process. By employing aspherical lenses in applications such as focusing the output from laser diodes, it is possible to reduce total costs and exceed the performance of assemblies designed with traditional spherical lenses. ■ For more details, please visit the official website of Edmund Optics via the link below.

basic information
Aspherical lenses require advanced optical design and manufacturing technology. Although they are expensive, they are widely used in many fields due to their optical performance and ability to correct chromatic aberration. Examples include photographic lenses, telescopes, microscopes, optical inspection devices, medical devices, laser devices, and space telescopes. Aspherical lenses can correct chromatic aberration more effectively. This allows different wavelengths of light to converge at nearly the same focal point, reducing color fringing and halo effects. Additionally, they offer higher optical performance and superior distortion correction capabilities compared to spherical lenses, while also achieving a more compact and thinner design.
