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...
Fresnel Lenses are Closely Related to Our Lives
At present, the main application fields of Fresnel lens include projection and solar photovoltaic field. Because the edge of the light penetrated through Fresnel lens is soft, it is often used in dyei...
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...
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...
Production Process of Cylindrical Lens
The production process of cylindrical lens mainly includes rough grinding, fine grinding, polishing, centering and edging.1. Rough grinding of cylindrical lensGenerally, the rough grinding of a small ...
What is the Difference Between Spherical and Aspheric Lenses?
1. The difference between spherical and aspheric lenses: surface curvatureThe difference between spherical and aspheric lenses: a spherical lens refers to a constant curvature from the center to the e...
Aspherical Lenses and Cylindrical Lenses
Ⅰ. Understand aspheric lensThe aspheric lens has a better radius of curvature and can maintain good aberration correction to obtain the required performance. The application of aspheric lenses brings...
The Principle of Achromatic Lens
Ⅰ. Introduction of achromatic lensAchromatic lens refers to an improved camera lens, which can reduce or eliminate the color difference. So that, different colors such as blue, purple, and yellow can...
Introduction of Aspherical Achromatic Lens
Ⅰ. Introduction of achromatic lensOrdinary achromatic lens refers to a lens group that corrects the color difference of light of three wavelengths such as blue, green, and red. Because the focus of t...
Understanding Apochromatic Lens and Its Applications
Introduction to Apochromatic LensA apochromatic lens can be defined as a lens made up of two different types of lenses with different focal lengths that cancel out apochromatic or color distortion. Ch...
Why Use Apochromatic Lens?
Apochromatic lenses are most commonly used in the form of doublet lenses. A doublet lens is made up of a pair of eyeglasses – one concave and the other convex. The concave element is made of flint gl...
Introduction and Application of Cylindrical Lenses
What is a cylindrical lens?A cylindrical lens is a lens with different radii on the X and Y axes, giving the lens a cylindrical or semi-cylindrical shape and magnifying images only along a single axis...
