Procedure Put the weak + 2.5 D lens in a holder at the far end of the mount or fix it firmly to the metre rule with Plasticine or Blu-Tack. If it is plano-convex, the convex face should be towards the object. WebPlano-Concave lenses bend parallel input rays to diverge from one another on the output side of the lens and hence have a negative focal length. They are the best choice when object and image are at absolute conjugate ratios greater than 5:1 and less than 1:5 to reduce spherical aberration, coma and distortion.
