Abstract
The invention relates to an apparatus for increasing depth sharpness and improving the resolving power of magnifying systems, particularly microscopes. An image-forming layer is inserted between the primary and secondary magnifiers of a composite magnifying system, in the optical path, after the object, in the image plane of the primary magnifier. The image-forming layer is comprised of independent particles dispersed in a medium, the index of refraction of which differs from that of said particles. The image-forming layer is disposed in the image plane, whereby the images coincide with the object plane of the secondary magnifier.
