Diffraction-limited singlet lenses

With the advent of optical disc systems, the need for compact, low-weight, and inexpensive microscope objectives has led to the development of small, well-corrected singlet lenses. The reduction of aberrations (mainly spherical aberration and coma) is achieved by the combination of mostly old ideas and new technologies like aspherical lens shapes, inhomogeneous lens material, and the application of holographic structures.
