摘要
A novel fabrication method for a 32-channel image slicer within the China Space Station Telescope[CSST]integral field spectrograph[IFS]is proposed,addressing challenges in multi-channel micro-slicer manufacturing.Our approach employs ladder stacking,polishing,and reverse stacking,combined with the Ritz method and blade crack propagation theory,to optimize molecular bonding and minimize deformation.This approach simplifies fabrication while ensuring high imaging quality,thereby meeting the requirements of CSST-IFS.This study advances precision optical instrument manufacturing and provides valuable insights for its future developments.
