Why Use Achromatic Lens?
Achromatic lens is a kind of lens which is made up of two kinds of optical components: positive low refractive index and negative high refractive index. Compared with a single lens containing only a s...
Quality Standard of Achromatic Lens
The difference between achromatic lens and other glasses is that as a part of optical system, it must meet the requirements of optical imaging. Therefore, the determination of the quality of achromati...
Does Achromatic Lenses have the Function of Heat Insulation?
In achromatic lenses, it is more important to pay attention to the application and design of hollow achromatic lenses (because glass occupies a larger area than aluminium alloy frames in curtain walls...
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...
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 ...
