What is the Transmittance of Achromatic Lens?
At present, there are many manufacturers producing achromatic lenses in China. Although the products of each company are called achromatic lenses, the raw materials and technology are quite different,...
The Benefit of Aspheric Lens-Spherical Aberration Correction
The most significant advantage of aspheric lens is that it can correct spherical aberration. Spherical aberration is caused by focusing or aligning light with a spherical surface. Therefore, in other ...
Additional Benefits of Aspheric Lenses
Although there are many different techniques for correcting aberrations caused by spherical surfaces on the market, these other techniques have far less imaging performance and flexibility than aspher...
Different Advantages of Each Aspheric Lens Type
Since the lens performance required for all applications is different, it is very important to choose an appropriate aspheric lens. Key factors to consider include your project schedule, overall perfo...
Advantages and Disadvantages of Aspherical Lenses
The surface radian of aspherical lens is different from that of ordinary spherical lens. In order to pursue the thinness of the lens, it needs to change the surface of the lens. Aspheric lens should b...
How to Design and Manufacture Aspherical Lens?
Aspheric fabrication is different from traditional spherical fabrication. In traditional spherical manufacturing, the surface is defined by a single radius of curvature. Curvature can be ground and po...
The Use and Storage of Doublet Lens
Doublet lenses are consumable. Aging begins immediately after opening the seal. During the long-term use, the surface of the doublet lens will continue to increase defects and stains. These defects or...
Manufacturing Method of Doublet Lens Curing Technology
More than 30 years ago, ultraviolet (UV) light was successfully applied in commercial applications. Various adhesives manufacturers have developed a series of UV products for bonding, sealing, printin...
Differentiation between Doublet Lens and Ordinary Lens
Doublet lenses are the most commonly used optical materials with mature manufacturing technology and complete varieties. Generally, doublet lenses can transmit colored light with wavelengths ranging f...
Analysis of Optical Lens
From the word light alone, we can see that it means bright and transparent. Optical lenses must have these attributes and have good transparency.Optical lenses are highly transparent, chemically a...
Grinding Technology and Classification of Optical Lens
In the process of plane planetary lapping, the uniformity of lapping disc wear is closely related to the lapping quality of optical lens. Based on the analysis of the motion law of optical lens in pla...
New Applications of Optical Lens Bonding
Optical manufacturers usually use mercury lamp UV ovens when they glue lenses to lenses. Now most optical factories have realized the concept of environmental protection and energy saving, as well as ...
Cold Processing Procedure of Optical Lens
The first way: milling, is to remove the uneven surface of optical lens bubbles and impurities, (about 0.05-0.08) play a forming role.The second process is to eliminate the damage layer of the milling...
Aspherical Lens are Lighter, Thinner, Flatter
The spherical lens is with a constant curvature from the center of the lens to the edge, while the aspherical lens changes continuously from the center to the edge. In photographic lenses, many aberra...
