Abstract :

Statement of the Problem: Reduction lens has been used in many applications for a long time. However, as the requirement for space limitations is the key issues of design, the fundamental theory for thin lens layout becomes crucial. The compact microreduction lens has only 10 mm total axial length, and 3 mm back focal length. The reduction ratio (image/object) is -0.212 and has diffraction image performance. Methodology & Theoretical Orientation: The design evolved from Seidel aberration theory. In finding initial solution for compact structures and long back focal length, a thin lens layout with â�?�?+, -â�? and â�?�?-, +â�? structures have been investigated. Findings: A thin lens layout with â�?�?+, -â�? configuration has less BFL than that of the â�?�?-, +â�? structureâ�?�?s. The axial glass length of the first lens can reduce air thickness for compact requirements and balance aberrations, which leading the high contrast performance of the reduction lens. Conclusion & Significance: The compact micro-reduction lens has designed based on Seidel aberration theories. An initial solution with â�?�?-, +â�? structure can balance the Petzval curvature aberration and have longer BFL for mechanical constraints. The image performance reaches diffraction limit under the -0.212 reduction ratio.
