Plano-Convex Lenses
Plano-Convex Lenses
A plano-convex lens is a convex lens with a positive focal length. This type of lens is used to focus parallel light or convert point sources into parallel light. And it is usually used in related applications such as narrowing beams of light, reducing the focal length or enlarging images. The coated lens is also widely used in the visible and near infrared fields.
