Low Mag Video Lenses 76 http://machinevision.navitar.com • email: info@navitar.comdistance are required in order to maximize contrast and performance. 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...

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...

In a video camera, the imaging element has a rectangular sensor area (the image size) that detects the image produced within the image circle. The ratio of the length of the horizontal to vertical sides of a video image is called the aspect ratio, which is normally 4:3 (H:V) for a standard video camera. Relationship Between Angle of View and Image Sensor Size An important...
