ABSTRACT:
A conical stage lens which receives and emits parallel rays of light and which can be used singly to produce magnified images and concentrated beams or in series to produce multiple magnified images and multiple concentrated beams. The stage lens consists of four component lenses, each with a refractive section (face) which widens the beam by 473 percent, this being the means by which enlargement of the object is accomplished.
When used as a microscopic lens, a lower component lens splits the image from the object into a wide annular image. Two middle component lenses refract the annular image outward, and a reflective cylindrical section forming the outer wall of the second middle component lens reflects the image inward to the upper component lens, where it is refracted a fourth time and emitted parallel to the incipient beam from the object.
