This product is a concave lens. The line connecting the centers of curvature on both sides is called the main axis, and the point O in the center is called the optical center.
The concave lens is also called a diverging lens. The focal length of a concave lens refers to the distance from the focus to the center of the lens.
The larger the radius of the lens, the longer the focal length, and if it is a thin lens, the focal lengths on both sides are equal.
PlanoConcave Lenses are ideal for beam expansion, light projection, or for expanding an optical system's focal length.
