A fixation lamp is described that enables a rational generation of panoramic fundus pictures with the Zeiss, Oberkochen, or other fundus camera of similar field, provided the patients collaborate. An illuminated marker at infinity is perceived centrally on the one hand, and on the other hand the marker is guided along a circle of 22 degrees eccentricity by a rotatable mirror system with click stops at every clock position 1 to 12 hours. If the camera is provided with angle scales, and use is made of its horizontal and vertical excursions, another circle of pictures at 38 degrees eccentricity can be obtained. With a total of 19 pictures a field of 96 degrees diameter is thus completely covered in a regular manner (see Fig. 6). Resolution wide-angle composite pictures of this kind is as good as resolution obtained by other means.
本文描述了一种固定灯，只要患者配合，就能使用蔡司公司（位于奥伯科亨）或其他具有类似视野的眼底相机合理生成全景眼底图像。一方面，无穷远处的照明标记在中央被感知到，另一方面，该标记由一个可旋转的镜子系统沿着22度偏心率的圆引导，在时钟的每个小时位置1到12处设有止动器。如果相机配有角度刻度，并利用其水平和垂直偏移，则可以获得另一组38度偏心率的图像。这样，总共19张图像就能以规则的方式完全覆盖直径为96度的视野（见图6）。这种广角合成图像的分辨率与通过其他方法获得的分辨率一样好。
