What is a Lens?
Lens is basically used to focus an image onto the sensor in a camera. All cameras have fixed sensor size. This means that no matter how large the image is at the sensor plane, the camera will only “look at” the portion of the subject equal to the sensor size. What the camera “sees” is called the field of view. The lens, or lens system, of the camera controls the magnification at the camera sensor.

There are many types of lenses. Some of the common categories of lenses are: CCTV, FA, Large format, Telecentric and Microscopic. These lenses have different functions and are therefore application specific.
