Performance Evaluation of Nano-JASMINE Telescope Flight Model

Abstract

The space astrometry satellite, Nano-JASMINE (Japan Astrometry Satellite Mission for Infrared Exploration), is a 5 cm diameter telescope designed to be sensitive to wavelength of zw-band (600< λ <1000 nm) and to achieve astrometry measurements of nearby bright stars (zw <7.5 mag) with an accuracy of 3 milli-arcseconds. This satellite will be launched by Cyclone-4 rocket from Brazil in 2013. A mission system flight model has been fabricated, and the performance has been evaluated; wave front errors were measured for the telescope mirrors and a radiation damage test was performed for a fully depleted charge coupled device image sensor used as a detector. This paper reports results of such a performance evaluation.
