Navitar has responded to this need with a wide range of fixed focal length lenses. Determining the necessary parameters for video lens selection, including focal length, field of view and image sensor size, does not need not be an intimidating process. An understanding of some basic optical terms and relationships is all that s required. The information on the following pages will help you select the lens that will work best for your application. If you require further assistance, please feel free to call Navitar and speak directly to one of our engineers.
Focal length is the distance between the camera sensor and the center of the lens.
The greater the focal length, the larger the image will appear. Therefore, the greater the focal length, the more the lens becomes telephoto in application. Standard Lens - A standard lens doesn t change the size of the object being viewed. Wide Angle Lens - A wide angle lens provides a wider field of view and therefore a smaller image of the object being viewed than a standard lens. The longer the focal length, the larger the object will appear.
