Abstract This paper summarizes the irradiation test results of three components selected from novel optical Rotman lens configuration to be used for beam forming and steering in airborne application. The components include the Rotman lens itself, a fiber with an attached graded index lens and a photodiode. All were irradiated up to a total dose of 20 krad using a 60Co gamma source. The components were found to be insensitive to this total ionizing irradiation dose. Later on similar photo diodes were irradiated at 62 MeV protons with fluence of up to and then measured after annealing of 17 days. No significant difference was observed in any of the parameters (measured after the gamma irradiation) with respect to a reference diode. Both experiments are indicating that the inspected components are potentially suitable for space.
