ID Code: L6-42
Purpose: Illustrate pincushion and barrel distortion and correction thereof.
Description: This is a two-lens system with an iris between, modeling camera or projector lenses. For the purpose of this demonstration there are apertures preceding and following the lens doublet. Closing only the preceding aperture results in barrel distortion, and closing only the following aperture produces pincushion distortion. Closing only the aperture between the two lenses results in no distortion.
