Peripheral astigmatism is a common lens problem that produces bright or dark spots in the peripheral areas. This is due to the shape of the lens so that light is scattered in different directions. Aspherical lenses can eliminate marginal astigmatism by adjusting the curvature, thereby improving imaging.

Standard AR coatings are the baseline for reducing lens reflections, improving vision in various lighting conditions. They typically include a basic scratch-resistant layer, offering a degree of protection against daily wear and tear. This option significantly enhances visual comfort by mitigating glare from artificial lighting and screens.

These lenses can focus light at short focal lengths that cannot be achieved with spherical lenses. Generally, it is made of B270-ultra-clear glass, so it is convenient to realize the manufacture of complex surfaces that are not easy to grind. The design condition of this type of lens is infinity conjugate, and the design wavelength is 587.6nm (yellow helium line). Condenser lenses concentrate light into a projection beam.

Mainly used in projectors, amplifiers, spotlights, and other projection and lighting fields. Two condenser lenses of the same focal length can be combined to form a system with half the focal length of a single lens. Primarily used in high-efficiency illumination systems, aspheric condensers feature excellent aberration correction.

When selecting an aspheric lens, it is necessary to consider aspheric lenses’ advantages and disadvantages to determine which lens is most suitable for a specific application.  Based on our experience of decades, the key factors into consideration include volume, quality, and cost.  Here, you can check the requirements for different types of lenses as follows:

Due to their complex design and manufacturing process, aspheric lenses are usually more expensive than traditional spherical lenses.

All AR coatings serve a fundamental purpose: to minimize light reflections on the lens surface, thereby enhancing visual clarity. They differ from polarized lenses, which are aimed at cutting glare from reflective surfaces. AR coatings reduce reflections directly on your glasses, allowing for greater light transmission and clarity.

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. Specifically, spherical lenses provide optimal imaging when the object is located at the infinity of the spherical lens.

Aspheric lenses, on the other hand, 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.

The use of aspheric lenses has two major advantages: one is to improve the imaging quality of the entire optical system; the other is to reduce the weight and size of the finished product. Advantages include a reduced number of back reflections that occur in the system resulting in higher total light transmission, reduced system heating when some kilowatt-level high power light is transmitted, advanced process technology reduces damage to subsurface layers, the spherical surface is precisely polished to improve the collimation accuracy.

UV light glue is a fast curing adhesive that can be used in daily repair. It is suitable for bonding metal, glass, ceramics, wood,

When exploring the options for prescription glasses at Optic One, customers are presented with a myriad of lens add-on choices. These range from high index lenses for stronger prescriptions to photochromic lenses that adapt to light conditions. A particularly beneficial option is the anti-reflective (AR) coating. However, making a choice between standard and premium AR coatings can seem daunting. This article is designed to shed light on the differences between these coatings, equipping you with the knowledge to make an informed decision for your next pair of glasses.

Aspheric lenses are designed to better correct spherical distortion, but they are also prone to other types of optical distortion, such as lateral astigmatism and longitudinal astigmatism.

Aspheric lenses have several advantages over conventional lenses, including improved accuracy in the light collection and the ability to eliminate spherical chromatic aberration. Additionally, they have a simple structure that can replace multi-lens systems, reducing weight, volume, and cost. Unlike traditional lenses, aspheric lenses have varying radii of curvature from the center to the surface’s edge. This unique feature enables them to eliminate errors that standard lenses cannot.

Aspheric lenses are unique lenses that have a non-spherical curvature. They are widely used because they can provide higher-quality imaging effects when compared with traditional spherical lenses. In this article by Noni, we will introduce what are aspheric lenses from their basic definition, compare them to spherical lenses, explain their working principles, and processing methods, list their advantages and disadvantages, and highlight their applications.

Aspherical lenses can be freely adjusted in curvature and shape as required, allowing them to provide higher optical efficiency. This makes them the preferred choice in many application areas, such as laser systems, lighting systems, and optical sensors.

In short, an aspheric lens is a lens that provides higher-quality imaging. They adjust curvature and shape to correct problems such as spherical aberration, distortion, and peripheral astigmatism and have the advantages of greater precision, larger aperture, and improved efficiency. Due to its wide range of applications, aspheric lenses will be more and more widely used in the future.

Spherical lenses produce spherical aberration in the peripheral region. This means that when light rays pass through the lens, they will be focused on different points due to different angles and positions, resulting in image distortion. Aspherical lenses can correct spherical aberration through complex curves, thus providing more accurate imaging effects.

Medical imaging also requires high-precision imaging to ensure accurate diagnosis and treatment. Aspherical lenses are widely used in the field of medical imaging, such as intraocular lenses in eye surgery, X-ray imaging systems, and MRI machines.

Our use of aspheric grinding CNC machine tools to produce lenses results in larger sizes, improved surface quality, and better maintenance of the M-square value of the input beam when compared to corresponding molded aspheric lenses. This technology is particularly suitable for small-batch production and product prototype manufacturing, thereby meeting the needs of diverse industries.

Conventional lenses also produce distortion in the peripheral region. This is due to the shape of the lens limiting how much light can be bent. In contrast, aspheric lenses can freely adjust the curvature as needed, thereby eliminating distortion.

Optical aspheric replication molding technology is a cost-effective and efficient method for manufacturing high-quality aspheric lenses. This technique involves transferring the surface of a master mold onto a base, resulting in the transformation of a spherical surface into an aspherical one. Unlike other aspheric surface processing methods, this technology requires minimal equipment and eliminates the need for substrate polishing, making it ideal for the mass production of sub-mirrors with identical specifications or spliced mirror surfaces.

While optical aspheric surface replication molding technology can achieve high precision and excellent surface quality, it may have limitations in terms of replication accuracy and surface quality. Therefore, it may not be suitable for all types of aspheric lens manufacturing needs. Nonetheless, when used appropriately, this technology serves as a valuable solution for various industries seeking to produce high-quality aspheric lenses efficiently and cost-effectively.

For the case where customized aspheric lenses are required, factors such as development cost, sample cost, batch price, and delivery cycle also need to be considered.

CNC grinding technology achieves sub-micron level precision in lens manufacturing and allows for more complex designs of aspheric lenses. Additionally, it provides higher production efficiency and superior surface quality compared to other methods, reducing production costs while enhancing lens performance.

Aspherical lenses offer many advantages over traditional spherical lenses, such as a more natural field of view and thinner and lighter designs. However, aspherical lenses also have some disadvantages, including:

Since aspheric lenses can freely adjust their curvature as needed, they can add relatively larger apertures while maintaining high imaging quality. This means that aspherical lenses can provide a larger field of view and a wider field of view in a smaller size, making them particularly suitable for photography and video applications that require high resolution.

The industrial field also requires high-precision imaging to ensure product quality and efficiency. Aspheric lenses can provide more accurate imaging in applications such as automated manufacturing, machine vision, and laser imaging, thereby increasing production efficiency and reducing costs.
