The greatest advantage of precision hot pressing is its ability to produce high-precision and smooth-surfaced aspheric lenses with sub-micron-level accuracy. Although the use of high-precision metal molds and materials that can withstand high temperatures and pressure may result in higher production costs. Furthermore, this method is ideal for producing relatively simple aspheric lenses due to the simplicity of their shapes.

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.

Expertise  Machine fleet audit and maintenance recommandations. Preventive services  Necessary care to maximize your machine lifetime.

Perfect for: precision engraving, detailed ink stamps, precision cutting on thin materials, high-resolution photos and logotypes (>800DPI).

The laser lens is the optical element of your machine that focuses the laser beam. The laser beam is between 8 and 10mm in diameter before the lens. The lens concentrates the beam at a thin point for greater precision and more concentrated power. This point is called the focal point.

Both spherical and aspheric lenses are common lens types, and the main difference between them is the curvature of the lens.

Aspheric lenses require more precise measurements and positioning, thus requiring more skilled operators during fabrication, installation, and adjustment.

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.

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 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.

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.

For their dedicated section in the New-York City NBA store, ISlide wanted to upgrade their already existing engraving solution with another machine that could have a better engraving quality, with a short engraving time and process.

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.

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.

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

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.

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.
