Abstract

Longitudinal-chromatic and -spherical aberration and lateral color are considered in various all holographic and hybrid diffractive/refractive lenses. These lenses include hybrid objectives,¹ dialytes, and separated configurations. Ray tracing and first-order analytic approaches are used in this analysis. Two-element hybrid dialytes are described which eliminate lateral or longitudinal chromatic aberrations. Applications of curved-holographic elements in simultaneously reducing both aberrations are discussed. A unique volume hologram aberration is discussed which is present even paraxially and is dependent only on wavelength change and element thickness. Low-scatter holograms have also been fabricated to illustrate some of these principles and to demonstrate the high-quality performance attainable.
