一种应用于眼科Nd:YAG激光治疗机的调焦光学系统

Focusing Optical Applied System to Nd:YAG Laser Disruptor for Ophthalmology

摘要: 该文设计了一种调节YAG激光焦点的光学系统，可以避免YAG激光手术时的人工晶体损伤。调焦光学系统采用扩束镜原理，采用螺线凸轮和蜗杆作为调节装置，使YAG激光的焦点在目标靶组织上在-500 μm~+500 μm范围内前后移动。

Abstract: In this paper, we design an optical system that can adjust YAG laser focus, and it can avoid the damage of intraocular lens in the YAG laser surgery. Focusing optical system uses beam expander principle, uses the spiral cam and the worm as adjust part, which can move YAG laser focus from -500 μm to +500 μm on the target tissue.
