Corneal reflections produce defects in photographic sections of the lens taken with a slit-lamp biomicroscope for computerized densitometric analysis of cataract opacity. A simple and workable, adjustable antireflection device was built that can be easily adapted to photographic slit lamps, a common instrument in ophthalmology equipment. The slit lamp is a versatile tool for photographing structures in the anterior segment of the eye, particularly the lens. Corneal reflections are eliminated for angles between the light band and a photograph plane ranging from 20 degrees to 90 degrees, with the light band no greater than 0.5 mm and the corneal curvature about 7.6 to 7.9 mm. The device acts by blocking aberrant light rays from the light source that would otherwise be reflected by the mirrorlike surface of the cornea and enter the objective lens. Here we present a prototype designed for the Zeiss slit lamp.
在使用裂隙灯生物显微镜拍摄晶状体的照片切片以进行白内障混浊的计算机密度分析时，角膜反射会产生缺陷。我们制作了一种简单可行、可调节的抗反射装置，它可以很容易地适配于摄影裂隙灯，这是眼科设备中常用的仪器。裂隙灯是用于拍摄眼前节结构，尤其是晶状体的多功能工具。对于光带与摄影平面之间20度至90度的角度，角膜反射可被消除，光带不超过0.5毫米，角膜曲率约为7.6至7.9毫米。该装置的作用是阻挡来自光源的异常光线，否则这些光线会被角膜的镜面表面反射并进入物镜。在此我们展示一款为蔡司裂隙灯设计的原型。
