【摘要】 介绍了一种分体侧立式YAG激光眼科治疗仪的光学系统。治疗头与裂隙灯显微镜光学系统相互独立，它具有二级扩束，He－Ne光对YAG光共轴指示，YAG激光焦斑直径dTAG＝（30±5）μm，光强度满足进行眼科手术的要求。更多还原

【Abstract】 This paper introduced the optical system of a kind of separate, side-standing type of YAG laser therapeutic instrument. The therapeutic head is independent from the optical system of the slit lamp microscope. It possesses two-stage beam expanding units, He-Ne laser guiding the YAG light. The YAG laser focal spot diameter dYAG= 30±5 μm, thus the laser power intensity meets the requirement for ophthalmological operation.更多还原
