WebbYet, because of the different shape of the double concave lens, these incident rays are not converged to a point upon refraction through the lens. Rather, these incident rays diverge upon refracting through the lens. For this reason, a double concave lens can never produce a real image. Double concave lenses produce images that are virtual. Webb10 jan. 2024 · Concave lenses diverge a straight light beam from the source into a smaller, upright virtual image. They can form both real and virtual images.
