Eksempler på focal length

• The aperture and focal length on the camera are set according to need.

• The procedure was applied to the 3 m focal length off-axis parabola.

• The focal length of the evolved system is 0.992298 and the sum of the distances is 0.09881 ($1/10).

• Therefore, the focal length becomes the key condition of the threshold producing the plasma in the condition of identical incident energies.

• The principle of choosing a focal length is to reduce the effects of the closure as weak as possible.

• The pixel pitch and the focal length of the cameras are 0.0185 and 2.5 mm, respectively.

• The focal length is longer for a low-intensity front.

• It may be necessary to set a larger focal length because of obstructions in the robot's path.
