Abstract
The invention is an eyepiece which is corrected for spherical aberration, coma, astigmatism, curvature of field, and longitudinal and lateral chromatic aberrations. The invention comprises a negative lens component, and two positive lens components, the components being spaced so that a real image is formed between the two positive components. Alternatively, the negative component and one positive component can be combined into a single thick positive component.
