Composition of Different Achromatic Doublet Lenses
1. Achromatic doublet lens is a kind of common lens. It consists of several groups of positive and negative cemented lenses with different radius of curved surface. It can only correct the axial chrom...
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 Forming Process of Aspheric Lens
1. Precision glass moldingPrecision glass molding is to heat the glass material to a high temperature to become plastic, shaping it through an aspheric mold, and then gradually cool it to room tempera...
What Makes Achromatic Lenses Important
Because achromatic lenses focus colors at the same point, they allow users to fully focus the image. Compared with uncorrected singlet lenses, achromatic lenses can produce clearer images, making it e...
Achromatic Lenses
1. The introduction of achromatic lensAchromatic lenses have various configurations, the most common of which are positive achromatic lenses, negative achromatic lenses, three-phase achromatic lenses ...
What Makes Apochromatic Lenses Important?
Because apochromatic lenses focus colors at the same point, they allow users to fully focalize the image. Compared with uncorrected singlet lenses, apochromatic lenses can produce clearer images, maki...
