8mm standard lens structure for 1 / 3-inch image pickup device

摘要

The present invention relates to an optical design as an 8MM standard lens structure for a 1 / 3-inch imaging device. As a technical problem, the 8MM lens so far has been expensive due to the use of wide-angle lenses developed for a 2 / 3-inch image tube. Therefore, a relatively cheap standard lens for 2 / 3-inch lens 16MM lens or semi-wide-angle beads 12MM lens was used. Henzo is used as a telephoto lens or semi-telephoto lens for 1 / 3-inch imaging device. There are many inconveniences. Development of 8MM standard lens for 1 / 3-inch imaging device is urgently needed.;The present invention solves the aberration by using the characteristics of each element lens to satisfy the field of view range of the 1 / 3-inch image pickup device while increasing the resolution and large-diameter ratio while reducing the number of components of the yoseo lens to 4 The lens is designed to be minimal.;Therefore, by developing a standard lens dedicated for 1 / 3-inch image pickup device, the price becomes cheaper, which is a great benefit not only for the manufacturer but also for the user.
