Example text

The object is well beyond the focal point on its side and the image is formed between one and two times the focal length on its side. smaller. If it is moved closer than 2F, the image will become larger than the object. Positive lenses, be they simple or compound, are used to form real images. LENS PROPERTIES AND MEASUREMENTS Modern lens makers have been able to achieve very high quality devices at surprisingly low cost compared to just a few decades ago. And, with all the improvements in both film and digital sensors, all the advances can be appreciated by the photographer.

In mechanical cameras, the image frame is fixed and the assembly that holds the lens is fixed relative to the plane of the image frame. If the key subject is to be brought into sharp focus, however, the distance between the lens and the image plane must increase as the key subject is placed closer to the camera. To accommodate a range of key subject distances, the mechanism holding the glass elements must be able to move relative to its mounting on the camera. When we change this location, we are adjusting the focus, or focusing the camera.

Camera lenses and magnifying glasses make real images whereas microscopes and telescopes make virtual images. In order to see the images from microscopes and telescopes, it is necessary to add another lens and make the combination produce a real image. If you look through the telescope, your eye lens is the additional lens, and what is produced is a real image on the retina on the inside of your eye. Another option is to add a camera and use the camera’s lens to create a real image on the sensor chip or the film in the camera.
