Abstract
A lens assembly suitable for use in miniature cameras is disclosed. The lens assembly can have a plurality of glass lenses having spherical surfaces and a single plastic lens having aspheric surfaces, for example. Optionally, all of the lenses can be disposed within a common lens barrel. A pupil plane can be located just in front of the first lens to provide a small chief ray angle. Both the cost of the lens assembly and alignment sensitivity are advantageously mitigated.
