Patent ID: 8248692

Claim:
A lens module, comprising: a barrel receiving a lens system therein; an infrared-cut filter; an infrared-pass filter; and a switching mechanism, comprising: a first magnetic member, a second magnetic member, and a connecting member interconnecting the infrared-cut filter and the infrared-pass filter; wherein the second magnetic member is fixed at the barrel, the first magnetic member is fixed at the connecting member and positioned generally opposite to the second magnetic member, and the first and second magnetic members are configured such that magnetic force can be selectively generated or absent therebetween to drive the connecting member to move relative to the barrel so as to selectively bring either the infrared-cut filter or the infrared-pass filter into optical alignment with the lens system in the barrel, the barrel has a top surface at an object side thereof, the second magnetic member is fixed at the top surface of the barrel, the connecting member is movably mounted to the barrel at the top surface, and the infrared-cut filter and the infrared-pass filter movably abut the top surface.
