Light rays reproduce an object, called an image, by gathering a beam of light diverging from an object point and transforming it into a beam converging toward or diverging from another point. If the beam is converging, it produces a real image.
SPHERICAL VS. ASPHERIC LENSES
HOW THEY’RE USED IN IMAGING APPLICATIONS
Optical Lenses are often categorized by their shape. Two common surface shapes are spherical and aspherical. Each offers unique characteristics that make it suitable for different use cases.
