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...
What are the Uses of Optical Filters?
Optical filters are a relatively unfamiliar concept for many people. They seem to be a little far from our daily life, but they are not. Looking closely at the surroundings, we will find that many asp...
Terms related to Optical Filters
1) Central wavelength (CWL): The wavelength used, such as the main peak of the light source is 850 nm led lamp, requires a central wavelength of 850 nm.2) Transmittance (T): Assuming that the initial ...
What are the Optical Glass Substrates for Filters?
Optical glass substrates of optical filters mainly include absorption glass, such as JB510, CB535, HB850, colorless optical glass K9, float glass, B270, fused quartz, etc.Geometric dimensions and thic...
What is a Bandpass Optical Filter?
In a certain band, there is only a small band with high transmittance in the middle and a high reflectivity cut-off band on both sides of the band. This kind of optical filter is collectively called b...
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...
