a Plot of encircled energy versus radius, per Zemax convention, where the dashed lines indicate that 86% of the laser light is encircled in a 38.5 μm radius. In conventional terms, this indicates a D86 spot size of 77 μm. b Modulus of the optical transfer function for the simulated ADM lens, detector, and composite system.
