Abstract

Zoom optical systems are versatile, serving applications from daily life, including photography, monitoring, and microscopy, to aerospace and national defense construction. With increasing applications, their performance standards are escalating. This paper introduces a 50mm-150mm three-configuration continuous zoom optical system. Employing a positive compensation structure, it achieves optical zoom in the visible band (390nm-760nm). Composed of six spherical glass lenses, it boasts a compact design with a total length of 40mm and a max aperture of 66mm, ensuring an F-number superior to 5 at long focal lengths. This system meets miniaturization demands while maintaining a high MTF (>0.32) across the entire field of view in the visible light band. The design fulfills high-performance criteria and offers valuable insights for the design of visible-band zoom optical systems with high magnification ratios and miniaturized footprints.
