Abstract
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.
