The beam radius is measured with a simple criterion, not based on the full intensity profile, although the beam profiles are not all close to Gaussian. Only for nearly Gaussian beam shapes, such simple measurement methods are allowed. For others, the D4σ method based on the second moment of the intensity distribution must be used.

Optical Surfaces. The lens application drives the requirements for surface irregularity and surface quality. When preservation of wavefront is critical, λ/4 to λ/8 irregularity should be selected; when wavefront is not as important as cost, λ/2 irregularity can be used. For surface quality, the tighter the scratch-dig specification the lower the scatter. For demanding laser and imaging ...

A high beam quality implies smooth wavefronts (i.e., strong phase correlation across the beam profile), such that focusing the beam with a lens allows one to obtain a focus where the wavefronts are plane. Scrambled wavefronts (see Figure 1) make beam focusing more difficult, i.e., the beam divergence for a given spot size is increased.
