Abstract (en)

[origin: FR2806170A1] The optical relay consists of front and rear convergent optical blocks (2, 3) and one or two meniscus correcting lenses (4) between them. Each meniscus lens has main faces which are preferably precisely concentric and the convergent blocks are located on the same axis (S). The front convergent block (2), located before the meniscus lens(es) is positioned so that a distance between an image point (I, I') of the system and the front block is equal to the focal length of the block, so that it converts a beam from the image point into a parallel beam.
