WebbA Fresnel with the lens open to show the ridges. There is no lamp in the instrument. A Fresnel lantern (pronounced frəˈnɛl or fruh-nel) is a common lantern used in theatre that employs a Fresnel lens to wash light over an area of the stage. The lens produces a wider, soft-edged beam of light, which is commonly used for back light and top light.
WebbThe convex lens converges the light rays at one point on the retina, hence it provides a clear and sharp image of the object. 2. Magnifying Glasses The most common use of convex lens is that it is used in magnifying glasses.
