The longitudinal chromatic aberration (LCA) specific to a high-harmonic multi order diffractive engineered (MODE) lens designed for the astronomical R band (589nm to 727nm) is described and demonstrated. This Type 2 LCA is characterized by rapid changes of focal position versus wavelength over a focal range of f0/M, where f0 is the design focal length at 658nm and M=2196 is the harmonic order. Type 2 LCA effects on image performance and correction methods are also discussed and demonstrated.
