What is claimed is: 1. A lens assembly for obtaining an image of an object, comprising: a lens device receiving a reflected light from the object; a circuit board carrying thereon the lens device; a spacer mounted on the circuit board; and a sensor mounted on the spacer, receiving the reflected light from the lens device and converting the reflected light into a digital signal, thereby generating the image, wherein a distance between the sensor and the lens device is adjusted to a focal length of the lens device by the spacer. 2. The lens assembly according to claim 1 further comprising a connector mounted between the circuit board and the spacer for conducting signals and currents coming from one of the circuit board and the spacer. 3. The lens assembly according to claim 2, wherein the connector is one of a conducting pillar and a conducting wire. 4. The lens assembly according to claim 1, wherein the lens device includes a lens tube and a lens base, and the lens base is used for mounting the lens tube on the circuit board. 5. The lens assembly according to claim 4, wherein the lens tube includes a plurality of lenses. 6. The lens assembly according to claim 5, wherein the lens tube further includes an end having a receptacle portion. 7. The lens assembly according to claim 6, wherein the end of the lens tube is mounted on the circuit board. 8. The lens assembly according to claim 7, wherein the receptacle portion is a notch. 9. The lens assembly according to claim 1, wherein the sensor is one of a CMOS optical sensor and a CCD optical sensor. 10. The lens assembly according to claim 1, wherein the lens assembly is an objective lens for a visualizer. 11. The lens assembly according to claim 1, wherein the spacer is a printed circuit board (PCB). 12. The lens assembly according to claim 1, wherein the circuit board and the spacer form a printed circuit board assembly (PCBA). 13. A lens assembly, comprising: a circuit board; a lens tube including a plurality of lenses; a lens base including a first end and a second end, the first end mounting thereon the lens tube and the second end mounted on the circuit board, wherein the second end further includes a receptacle portion; a spacer horizontally mounted above the circuit board and within the receptacle portion; and a sensor mounted above the spacer and receiving a focused light formed from the plurality of lenses, wherein a distance between the sensor and the lens tube is adjusted to a focal length of the lens device by the spacer. 14. The lens assembly according to claim 13 further comprising a connector mounted between the circuit board and the spacer for conducting signals and currents coming from one of the circuit board and the spacer. 15. The lens assembly according to claim 14, wherein the connector is one of a conducting pillar and conducting wire. 16. The lens assembly according to claim 13, wherein the sensor is contained within the receptacle portion. 17. The lens assembly according to claim 13, wherein the sensor and the spacer have a cooperative size smaller than a containing space of the receptacle portion. 18. A lens assembly, comprising: a circuit board; and a lens device disposed on the circuit board and including a receptacle portion containing a spacer and a sensor disposed above the spacer, wherein a distance between the sensor and the lens device is adjusted to a focal length of the lens device by the spacer. 19. The lens assembly according to claim 18, wherein the spacer is horizontally disposed above the circuit board. 20. The lens assembly according to claim 18, wherein the sensor receives a focused light from the lens device.
