Gradient-index objectives for CD applications.
The application of gradient-index (GRIN) lenses in an optical scanning system (e.g., a Compact Disc player) is investigated. The type of lens considered varies from simple rod lenses to plano-convex and convex-convex lenses. The field performance of the lenses and the relations between their thickness, surface curvature, base index, and index profile are given.
