Plano-convex lens is also called negative Ball Lens, the middle of the lens is thick, the edge is thin, and it is convex, so it is also called convex lens. Convex lens converges light. Concave lenses are divided into Double Convex Lens, double convex lens, and convex-concave lens. What are the applications of Plano Convex Lens in life?he application of convex lens in life 1. Camera: The camera lens is a convex lens, and the film is equivalent to a light curtain. When shooting a scene, make the distance from the scene to the lens far greater than twice the focal length. 2. Projector: The lens of the projector is a convex lens; when the slide is illuminated with strong light, an upside-down, magnified real image can be obtained on the screen. In order to make the resulting image "upright", the slide should be upside down. Note: For cameras and projectors to make the image larger, the lens should be close to the object and away from the film and screen. 3. Magnifying glass: The magnifying glass is a convex lens; if the object is placed within 1 times the focal length of the convex lens, it can be an upright magnified virtual image. 5. Reading glasses It is used to correct the vision of presbyopia, using the condensing effect of the convex lens to form an image on the retina. 6. LED flashlight For living lighting, the light source is located at the focal point and becomes a parallel beam principle after being refracted by a convex Spherical Lenses . 7. Solar cooker Used to heat food, the convex lens condenses light. In addition to the examples mentioned above, convex lenses have many other applications in daily life. For example, telescopes are all convex lenses.
