In the first study, it is found that three IOL proved to improve visual acuity after cataract surgery, while the second study showed that Tecnis Z9000 had the least optical aberrations.Chu,...
Gold Dragon Optics offers aspheric lenses to suit many applications. An aspheric lens can be offered with a range of coatings for the Ultraviolet (UV) spectrum, visible light, or Infrared (IR) spectrum. Aspheric lenses utilize a single element design which helps minimize the number of lenses ...
Aspheric lenses have a slimmer profile for virtually all prescriptions, but the difference is especially dramatic in lenses that correct high amounts offarsightedness. Lenses that correct farsightedness (convex or "plus" lenses) are thicker in the center and thinner at their edge. The stronger t...

Aspheric lenses have at least one surface defined by an aspheric equation that has a fluctuating local radius across the diameter of the part. As a result, this creates an optical lens with a non-constant radius around the sphere. Aspheric Lens Manufacturing Draw on LaCroix's 75+ years in ...

Aspheric lenses have non-spherical shapes, and have a more complex front surface, such as ellips, parabola, hyberbola, quadric, etc. Specification Substrate Optical glass or plastic Size 3-460mm Thickness 1-30mm Coating AR coating Tolerance ...
Aspheric lenses have unique advantages over spherical lenses. For example, they can improve optical quality, reduce optical components and design costs. They are widely used in optical instruments, images and optoelectronics industries, such as digital cameras, CD players and high-end microscopic ...
