Abstract
A lens module includes a carrier, a framework, and an optical lens disposed on the framework. The carrier has an inner surface including a contact surface. The framework contacts the contact surface and is configured with a guiding lever disposed in a guiding recess formed across the inner surface. When the guiding lever is moved in the guiding recess, the framework is rotated on the carrier about an optical axis, and the framework and the optical are moved on the carrier along the optical axis. A projection apparatus includes an illumination system, a light valve, and a projection lens, and the illumination system includes the lens module. The lens module and the projection apparatus may be used to adjust the focusing position of the light beam passing through the optical lens to a proper position, and improve the projection quality of the projection apparatus.
