Cylindrical Lenses > Cylindrical Plano Convex Lens BK7

Introduction

Cylindrical lenses are used in applications requiring magnification in one dimension only. These lenses follow the same theory and formulas as spherical lenses although they image in only one dimension not two. Cylindrical lenses are used to transform a point image into a line image and to change image height without changing width or vice versa.
