A miniaturized Cassegrainian concentrator module for space applications has been designed, assembled, and tested. Results to date support technical feasibility. Trade studies have shown that the performance of an earlier selected baseline design using silver coated, 0.25 mm electroformed nickel optics with circular elements arranged in a hexagonal close packed configuration can be improved. Specific power values of 27.3 W/kg BOL and 25.0 W/kg after 5 years in LEO have been projected at the 4 kW array level. At the 500 kW level, 20 W/kg BOL had been predicted earlier for the same cell efficiency.
