Is a Aspherical Camera Lens Better than a Spherical Lens?
The asphericWhen it comes to the lens, you have to mention the aspherical lens. In many people's understanding, the aspherical lens is a symbol of high level, and the advanced lens is almost all asphe...
Calcium Fluoride Lenses
Calcium fluoride lenses can also be fluorite lens. Fluorite is made of CaF2 crystal. Its obvious characteristics are low refractive index and dispersion, good transmittance for infrared ray and ultrav...
Collimator Lemses Achieve Efficient Lighting
Researchers from information photonics laboratory of Xi’an institute of optical precision machinery, Chinese academy of Sciences have designed collimator lenses with efficient lighting for Led. Recen...
How to Judge whether Achromatic Doublet Lens is Good or not?
Achromatic doublet lens is a kind of glass that can change the direction of light transmission and the relative spectrum of ultraviolet, visible or infrared light. In the narrow sense, achromatic bi-...
What is the Cleaning of Achromatic Doublet Lens Film?
The cleaning of achromatic doublet lens can be divided into pre-coating and post-coating. Processors should adopt different cleaning methods according to the different pollutants before and after coat...
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...
