What is Lens Focal Length. Focal length, usually represented in millimeters (mm), is the basic description of a photographic lens. It is not a measurement of the actual length of a lens, but a calculation of an optical distance from the point where light rays converge to form a sharp image of an object to the digital sensor or 35mm film at the focal plane in the camera.

2.When using the Lens Equation, a virtual image has a a. positive object distance b. negative image distance c. positive image distance 3.The scale at the bottom of the diagram is calibrated in cm. Find the focal length of the lens (in cm). Ray Diagram for Object Located in Front of the Focal Point. In the three cases described above - the case of the object being located beyond 2F, the case of the object being located at 2F, and the case of the object being located between 2F and F - light rays are converging to a point after refracting through the lens. In such cases, a real image is formed. If the bottom half of a diverging lens is covered, then the bottom half of the image will not be visible. Diverging lenses only produce virtual images. Diverging lenses can produce images which are both magnified and reduced in size. Diverging lenses only produce upright images. Diverging lenses have a - focal length.

If a concave lens of focal length 20 cm is placed between the covex lens and the image at a distance of 26 cm from the convex lens,calculate the new size of the image[2003-2 marks] a) 1.25 cm b) 2.5 cm c) 1.05 cm d) 2 cm Ans. Ans. Focal length: the distance from the middle of the camera lens to the focal plane (i.e. the film). As focal length increases, image distortion decreases. The focal length is precisely measured when the camera is calibrated. Scale: the ratio of the distance between two points on a photo to the actual distance between the same two points on the ...

Practice Scale Computation Example: Aerial imagery was acquired with a digital aerial camera with lens focal length of 50 mm and CCD size of 0.020 mm (or 20 microns). The resulting imagery had a ground resolution of 60 cm (2 ft). Determine the scale of the resulting imagery. Solution. Scale = 0.020 mm 60 cm x 10 mm/cm = 0.020 600 = 1 30, 000 centimeters.

A concave mirror with focal length 10 cm is located 75 cm to the right of the lens as shown in the figure. Note: The figure is not drawn to scale. Determine the location of the final image. example, if the object distance is four times the focal length, the magnitude of the magnification is 1/3, regardless of the exact values of the object distance and focal length. Hint C.2 Object at the focal point If an object is located exactly at the focal point, the image is "infinitely" large.

The positive meniscus lens (Figure 1(c)) has an asymmetric structure with one face shaped as a convex radius, while the opposite face is slightly concave. Meniscus lenses are often employed in conjunction with another lens to produce an optical system having either a longer or shorter focal length than the original lens.
