Web17 aug. 2011 · Suppose the laser pointer beam is nearly collimated: you measure a divergence of 0.3 milliradians, about 0.017 degrees. Then the waist size is w 0 = M 2 λ π Θ = 1.5 × 671 × 10 − 9 π × 3 × 10 − 4 ≈ 1 mm. In this case, they probably designed the laser pointer with an aperture radius of 2 or 3 mm. WebFirst let us write down the formula for calculating this range and then try some numbers. DOF = 2.5 x wavelength x ( f /D )2. where D is the beam diameter and f is the focal length of the lens. For CO 2 laser (wavelength = 10 micron = 0.01 mm), this becomes: DOF (in mm) =0.027 x ( f / D )2. Example 1: eartha griffin
