The use of aspheric lenses can result in improved image quality, with sharper and clearer images and increased resolution. Aspheric lenses can also reduce the size and weight of optical systems, as they can correct for multiple aberrations with a single lens. This is because aspheric lenses can reduce spherical aberrations, distortion, and field curvature, which are often present in traditional spherical lenses.

Another advantage of aspheric lenses is their ability to reduce chromatic aberrations. Chromatic aberrations occur when different colors of light are focused at different points, causing a rainbow-like effect around the edges of an image. Aspheric lenses can reduce this effect by controlling the refraction of light at different wavelengths, resulting in a more accurate and consistent focus for all colors of light.

Fragility: Aspheric lenses are often made from thinner and lighter materials compared to spherical lenses, which can make them more fragile and susceptible to damage.

Freeform Optics: Freeform optics is a production method that is used to produce complex aspheric lenses with low to medium volume production runs. This method involves using advanced computer-controlled machinery to machine the lens material to the desired aspheric shape. The surface quality of the lens produced using this method is typically higher than that produced using other production methods, and it allows for precise control of the lens surface.

Spherical Molding: Spherical molding is a production method that is used to produce simple aspheric lenses with low volume production runs. This method involves pressing a heated lens material into a spherical mold, which then deforms the lens material into the desired aspheric shape. The surface quality of the lens produced using this method is limited, and additional surface finishing is typically required to achieve the desired surface accuracy.

The production of aspheric lenses involves several steps, including the design and prototyping of the lens surface, molding or grinding of the lens surface, and coating of the lens surface to increase its transmission. The design of the aspheric surface is determined by mathematical equations that account for the desired correction of aberrations and the desired image quality. The lens surface can be molded or ground to the desired shape using a variety of techniques, including grinding, diamond turning, and injection molding.

Limited Availability: Aspheric lenses may not be available in certain sizes or configurations, which can limit their use in certain applications.

Resolution: 1024 × 1024 Pixel size: 10 µm Extreme performance in high frame rate ultra-low light applications

The spherical shape of traditional lenses is determined by the radius of curvature of the lens surface. In order for light to be focused correctly, the surface must be a perfect sphere. However, this shape can cause aberrations that limit the resolution and contrast of the image. Aspheric lenses are designed to overcome these limitations by modifying the shape of the lens surface to correct for aberrations.

The surface profile equation can be expressed as a polynomial or a more complex mathematical function. The coefficients of the polynomial or the parameters of the mathematical function are chosen to produce a lens surface that corrects for the desired aberrations.

Aspheric lenses can be made using a variety of materials, including glass, plastic, and other optical materials.

Spherical aberrations occur because of the difference in the refractive index between the center and the edge of a spherical lens. Light passing through the center of the lens is focused to a single point, but light passing through the edge is not focused correctly, leading to a blurred image. This effect is more pronounced for lenses with a large aperture, such as camera lenses or telescopes.
