照相物镜光学设计 （ f’=50mm） The Optical Design of Objectiv e Lens in Photographic Camera (f’=50mm) 2 摘要 人们早就有长期保存各种影像的愿望。在摄影技术尚未发明前的公元四世纪时，人们按投影来描画人物轮廓像的方法达到了全盛时代，至今这种方法仍然作为剪纸艺术流传着。后来，人们让光线通过小孔形成倒立像，进而将小孔改为镜片，并加装一只暗箱。只要在暗箱底板上放一张纸，不仅可以画出轮廓，还可以画出像上的各个部分。这就形成了照相机的机构雏形。 随着科学技术的发展，照相机的发展日益迅速，有着显著的飞跃。照相物镜是照相机的眼睛，它的精度和分辨率直接影响到照相机的精度与成像质量。要保证所设计的照相物镜达到较高的技术要求，在设计时就必须达到更高的精度与分辨率。本文所讨论的照相物镜，它主要采用五片透镜包含一个双胶合透镜的形式，精度高、分辨率高，像质好，能够满足设计的要求。 关键字： 照相机 物镜 设计 3 ABSTRACT The people already have the long-term preserved each kind of phantom desires. Not yet invents before when the photographic technology the A.D. four centuries, the people drew the character outline alike method according to the projection to achieve the most flourishing time, this method still was spreading until now as the paper-cut art. Afterwards, the people let the light form through the eyelet stand upside down the elephant, then changed the eyelet the lens, and installed a camera. So long as puts a paper on the camera ledger wall, not only may draw the outline, but also may draw likely on each part. This has formed the photographic camera organization embryonic form. Along with the science and technology development, the photographic camera development is day by day rapid, has the remarkable leap. The photographic objective is the photographic camera eye, its precision and the resolution affect directly the photographic camera precision and the image formation quality. Must guarantee designs the ...
