Claim:
A lens module, comprising: a plurality of optical components; a barrel receiving the optical components therein; a holder having a cavity therein for holding the barrel; a filter base disposed at the barrel, the filter base comprising a main body and two opposite catch protrusions each comprising a main portion and a bent portion, the main portion extending from the main body along a direction substantially parallel with a central axis of the barrel, the bent portion extending from an end of the main portion toward the other catch protrusion along a direction substantially perpendicular to the central axis of the barrel; a filter carrying member movably mounted on the filter base in such a manner that the filter carrying member is disposed between the two catch protrusions and substantially in slidable contact with the main body and the bent portion and the main portion of each catch protrusion; an infrared-cut filter; and a visible-light-cut filter; the infrared-cut filter and the visible-light-cut filter being mounted on the filter carrying member which 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.
