In the optical assembly industry, reducing the number of lenses is the first factor to consider in design, and choosing a single lens is a good solution.
For example, our chromatic aberration correction aspherical lens can simultaneously reduce both spherical and chromatic aberration. When traditional lenses are used, due to the passage of different wavelengths, color difference will occur at different points on the optical axis, and the color difference will be more pronounced after passing through multiple lenses. The color difference correction of aspherical lenses using different materials of glass can be offset by different refractive indices. By using this type of lens, the number of lenses in the entire optical system can be minimized to the greatest extent, not only reducing the system size, but also reducing the total weight and cost, making assembly more simple and efficient.
