摘要
手术显微镜目镜出瞳光的显色指数直接影响显微镜的观察效果,目前标准中未对该指标进行要求。为了研究手术显微镜目镜出瞳光与物面照明光的显色指数差异,本研究测量了两台手术显微镜在分别配合不同光源和不同目镜时,物面照明光和目镜出瞳光的显色指数差异。结果表明目镜出瞳光的显色指数均低于物面照明光,且同一目镜对于不同手术显微镜的影响不同,在实际应用中应合理选择光学系统以提高手术显微镜的观察效果。
The color rendering index（CRI） of eyepiece exit pupil light in surgical microscope directly affected the observed effect. The current standards had no requirements about the CRI of eyepiece exit pupil light. To study the difference of the CRI between the eyepiece exit pupil light and the object illumination light, the research measured the CRI of the eyepiece exit pupil light and the object illumination light in two surgical microscopes with different light sources and eyepieces. According to the results, the CRI of eyepiece exit pupil light was lower than the object illumination light; the same eyepiece impacted differently in different surgical microscopes. In practice, the optical system should be taken as a reasonable choice to improve the observed effect.
