Custom Aspheric Optics

Why Aspheric Optics

Aspheric optical components offer unparalleled imaging quality compared to spherical optical parts, effectively correcting various aberrations present in the system. This results in improved imaging quality and enhanced system resolution.

By replacing multiple spherical components with a single aspheric part, the instrument’s structure is simplified, leading to cost and weight reduction. Aspheric optics provide not only superior performance but also contribute to compactness design of optical instruments. Their ability to optimize system makes them highly sought after in various applications.

Aspheric Lens VS Spheric Lens

The major difference between spherical and aspherical lenses is the curvature of the lens. Spherical lenses have the same curvature, while aspheric lenses have different curvatures.

Due to the fixed surface curvature of spherical lenses, they only provide the best image quality in certain situations. However,aspheric lenses can be manufactured in a variety of curvatures as needed, so problems such as spherical aberration, distortion, and peripheral astigmatism can be better corrected, making them better adaptable to various imaging needs.
