Product Description

Traditional spherical lenses will produce spherical aberration. Spherical lenses have undesirable characteristics (called spherical aberration). This characteristic causes the light to be diffracted the farther away from the optical axis of the lens. Spherical aberration leads to a decrease in image clarity. Aspheric lenses The shape is optimized for excellent imaging properties. The main advantage is the ability to correct spherical aberration. Aspheric lenses can not only effectively eliminate spherical aberration, but also eliminate other forms of aberration produced by the lens.
Aspheric lenses are single element designs that help reduce the number of lenses in multi-lens optical assemblies. In other words, unlike traditional lenses, which have a spherical shape, aspheric lenses have more complex surfaces. The reduction in total component count not only helps reduce system size or weight, but also simplifies the assembly process. In this way, its structural design is more compact and more powerful than similar systems based on spherical lenses. Incorporating aspherics into applications such as focusing the output of laser diodes not only reduces overall cost, but also outperforms components designed using traditional spherical Optical Lenses.
