Aspherical lenses have many properties that often make them a preference in an optical system. Firstly, by shaping the surface to a more complex curvature, and not a traditional spherical surface, aberrations within the system can be minimised – especially spherical aberration, as well as coma and astigmatism. In a traditional lens system utilising spherical lenses multiple lenses are often required to reduce the aberrations that one aspheric lens can achieve. This allows for a more compact design, as fewer optical elements are needed.

Aspherical lenses are used in a multitude of applications where factors such as image quality, compact design, and reduced aberrations are fundamental. Applications include telescopes, laser systems, medical imaging, virtual reality (VR) and augmented reality (AR) headsets, defence and aerospace, and automotive imaging systems.

Using the capabilities of aspherical lenses, laser beam shaping achieves unparalleled focus and direction, ensuring optimal energy distribution and enhanced performance in applications.

Imaging systems, particularly those employing CCD/CMOS image sensors, greatly benefit from the precision and clarity offered by aspheres.

Knight Optical has been operating for over 30 years, with our managing director Colin Overton at the helm. Over this time, we have become a global leader in the production and distribution of scientific optical components and bringing quality into focus for all of our products and services that we provide.

An aspheric lens and a spherical lens are optical elements with different types of surface curvatures. A spherical lens has a surface that forms part of a sphere and the curvature is constant across the whole surface. An aspherical lens has a curvature that varies across the surface, defined by a sag equation, which allows for more flexibility in the lens design to optimise the performance of the lens for a specific application.

Using aspherical lenses can streamline optical systems, eliminating the necessity for multiple lenses. This not only trims down the system’s weight but also results in significant cost savings.

Microscope objective lenses designed with aspherical lens elements boast a more compact design, offering a distinct size advantage over traditional spherical counterparts.

By using aspherical lens elements, fibre optic applications experience improved signal clarity and transmission efficiency, making them ideal for high-bandwidth data communication networks.

An aspherical lens element is used to correct for spherical aberrations, where the converging rays from a lens do not have a common focal point. This is an issue often seen in traditional spherical lenses.

Knight Optical is proficient in crafting achromatic aspherical lenses that offer superior colour correction. By using aspherical optics, we ensure clarity and precision in every lens.

An aspherical lens element has a more complex surface curvature compared to a traditional spherical lens, whose surface is part of a perfect sphere. This deviation from a sphere allows for correction of optical aberrations, such as spherical aberration, within the optical system, as the light rays are focused to a more precise point. This occurs as the curvature changes from the centre point and therefore as does the refraction of light through the surface, allowing the rays to focus more tightly. This surface curvature is defined by a sag equation and produces a sharper and improved image quality.
