Manufacturing and testing of rectangular off-axis aspheric mirror with double-swing polishing method
摘要
Abstract
A kind of manufacturing and testing method for rectangular off-axis aspheric lightweight mirror is in-troduced.In order to overcome the corner effect, double-swing polishing( DSP) method is proposed.A DSP machine is made to achieve satisfying manufacturing result.The DSP and the 4-pole method are successfully applied for manufacturing optical system in the spectrometer.Four rectangular off-axis aspheric mirrors with the largest size of 266 mm ×110 mm are polished, and the final surface precision figures are better than 0.020λ( RMS,@633 nm) .Manufacturing result shows that the double-swing polishing method improves the polishing efficiency and reduces the optical surface medium frequency error.关键词
