The Tube-Length Extended Technic For Wide-angle Galilean Non-Power System

    Graphical Abstract
    • Abstract
  • The tube-length is inversely proportional to viewing field-angle Galilean non-Power.This paper presents the tube-length extended technic basing theory of muti-lens and multiply,in order to satisfy wide-angle condition to attain serviceable tube-length.And states constracting restriction of objective and negative ocular,when constraints distortion and pledge to some interpupillary distance,as well as the systematic aberration balancing method.
