Aspherical Lenses Aspherical Camera For Photography

Aspherical lenses are lenses with a non-spherical surface. Their aspheric shape corrects for spherical aberration, allowing light rays to focus at a single point. They correct for spherical aberration through their non-spherical surface profiles. Though more complex to produce, they offer significant advantages for optical performance, size reduction, and cost in many applications. Continued progress in manufacturing technologies and design methods has made aspherical elements critical for modern, high-quality lens systems.

 

As a leading lens manufacturer, we have pioneered the production of precision aspheric lens elements. We craft high-quality aspherical lenses with micron-level surface accuracy using state-of-the-art CNC grinding, polishing, and metrology equipment in our climate-controlled facility. Our experts optimize each asphere’s non-spherical surface profile to correct for spherical aberration in your optical design precisely. The result is a lens tailored to your needs that reduces aberrations, enhances resolution, and helps shrink system size for more compact products.

What is the difference between an aspherical and spherical lens camera?

The main differences between aspherical and spherical lens cameras are:

• Aberration correction - Aspherical lenses have non-spherical surfaces designed to correct for spherical aberration and other optical aberrations. Spherical lenses have evenly curved spherical surfaces that do not correct for aberrations, resulting in imperfect focusing and image defects. Aspherical camera lenses produce sharper, higher-quality images with less aberration.

 

• Compactness - Aspherical elements allow shorter focal lengths and lens barrels, resulting in more compact camera and lens designs. The same focal length and aperture can be achieved in a smaller size. Spherical structures require more lens elements to perform similarly, yielding bulkier optics.

 

• Aperture - The aberration correction of aspheres allows for larger maximum apertures (lower f-numbers) without significant loss of image quality. This enables photography in lower light conditions. Spherical designs cannot achieve as large apertures without significant aberration and softness.

 

• Field of view - Aspherical optics facilitate wider angle of view or zoom range lenses while maintaining good edge-to-edge sharpness. Spherical designs are prone to field curvature, astigmatism, and other off-axis aberrations, especially at short focal lengths.

 

• Price - Aspherical lens elements are more complex and challenging to manufacture, so they are typically more expensive than comparable spherical lens elements and overall lens designs. Their price has declined with advances in production methods, but aspheres still represent a price premium.

 

• Performance - Overall, aspherical lenses yield significant performance advantages over basic spherical designs for most photographic applications. Their ability to minimize aberrations and maximize resolution across the image field has made aspheres critical to state-of-the-art optics. Most high-end professional cameras now rely on aspherical elements for optimal image quality.

However, spherical lens designs still have some benefits:

 

• Simplicity - Spherical elements are more straightforward, easier to produce and align, and cheaper than aspheres. They can perform well for more extensive focal lengths where aberrations are less prominent.

 

• Durability - Spherical elements typically have thicker, more rounded profiles that may make them less vulnerable to damage under some circumstances. Aspheres often have a more delicate curved surface and edge.

 

• Affordability - Spherical lenses can provide acceptable quality at a lower cost for some compact, consumer-focused cameras where ultimate performance is not critical. They suffice for basic photography.
