WebbThe Rayleigh range of a Gaussian beam is defined as the value of z where the cross-sectional area of the beam is doubled. This occurs when w (z) has increased to √2 w 0. Using Equation 4, the Rayleigh range (z R) can be expressed as: (5)zR = πw2 0 λ z R = π w 0 2 λ. This allows w (z) to also be related to z R: WebbThe magnification produced by a lens can be calculated using the equation: \[magnification = \frac{image~height}{object~height}\] Magnification is a ratio of two … commonwealth national life insurance company
