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...
What Are the Functions and Uses of Laser Beam Expanders?
Understanding Laser Beam ExpandersA beam expander, also known as a collimator, is a commonly used Galilean telescope system that usually consists of a negative lens and a positive lens, both of which ...
