What is a lenticular lens?

A lenticular lens is a specialty lens consisting of a series of tiny optical lenses, which are placed next to each other on the surface of a plastic film or sheet. Each lens has a specific shape and size, and is designed to refract light in a unique way.

When viewed from different angles, a lenticular lens can create a variety of visual effects, such as 3D images, animation, or morphing. These effects are achieved by printing a series of images or patterns on the back of the lens, and then aligning them in a specific way to produce the desired effect.

Lenticular lenses are commonly used in a variety of applications, such as advertising, packaging, and entertainment. They can be found on products such as posters, book covers, business cards, and even on the screens of some smartphones and tablets.

Overall, lenticular lenses are a fascinating technology that offer endless possibilities for creative expression and visual communication.
