Aspheric Lenses www.shanghai-optics.com. Click here to learn more about aspheric lenses. Why Asphere?. As the name suggests, an aspherical lens is a lens with a shape other than that of a regular sphere or cylinder. These lenses, which come in a variety of shapes, are used to correct spherical aberration and enhance image quality. Spherical aberration is a type of defect that occurs when light passes through a spherical surface. Depending on how close to the edge it enters the lens, light focuses at different...

Aspheric Lenses Types of Aspheric Lens. An aspheric lens may have any of a number of geometries. Most aspheric lenses are rotationally symmetric but have a more complex front surface. Unlike a spherical lens, the curvature changes with the distance from the optical axis. Another way of putting this would be to say that the radius of curvature varies radially from the center of the lens. Typically, the further from the optic axis, the weaker the curvature. A lens that does not have these symmetries is typically... (read more)Browse Aspheric Lenses Datasheets for Avantier Inc. -
