Occasionally we are interested in how the addition of a flat "glass" plate downstream from an image-forming lens shifts the location of the plane of focus. This comes up, for example, in the matter of the addition of a fresnel field lens in front of the ground glass in a vew camera.
I have just relased to my technical information site, The Pumpkin, a new tutorial article entitled, "The Effect of Inserting a Flat Glass Plate into the Optical Path Downstream from a Lens". It is available here:
