Description

Biconcave Lens 50 mm Diameter, Focal Length 20 cm

A biconcave lens with a 50mm diameter and a focal length of 20cm are thinner at the center than at the edges, causing light rays passing through them to diverge. This property is useful in physics experiments and demonstrations where diverging light is needed. When an object is placed beyond the focal length of a concave lens, it forms an upright, virtual, and diminished image. This property is used in optical devices like magnifying glasses and cameras to reduce the size of an image. In optometry, concave lenses are used to correct nearsightedness (myopia). They help diverge light rays before they reach the eye’s lens, allowing the image to focus correctly on the retina. Ideal for teaching principles of optics, such as refraction, focal length, and lens combinations.
