ABSTRACT:
An exemplary lens module includes a number of optical components, a barrel, a holder, a filter base, a filter carrying member, an infrared-cut filter and a visible-light-cut filter. The barrel is configured for receiving the optical components therein. The holder holds the barrel therein. The filter base is disposed in the barrel. The filter carrying member is movably mounted on the filter base. The infrared-cut filter and the visible-light-cut filter are mounted on the filter carrying member. The filter carrying member is movable relative to the filter base so as to selectively bring either the infrared-cut filter or the visible-light-cut filter into optical alignment with the optical components in the barrel. The lens module can be capable of performing infrared and visible-spectrum photography.
