Omnidirectional zoom optical system that can be used in day and night and can change magnification

摘要

The present invention relates to an omnidirectional zoom optical system, and more specifically, to an omnidirectional zoom optical system in which there is no chromatic aberration, excellent imaging performance, and an angle of view changes according to a change in magnification by using four mirrors. The present invention can provide an omnidirectional zoom optical system capable of reducing the size of a product by using four mirrors without chromatic aberration, excellent imaging performance, and shortening the length of the optical system. In addition, the present invention can provide an omnidirectional zoom optical system capable of simultaneously using a visible light region and a far-infrared ray region at the same time as the angle of view changes according to the magnification change through the movement of the mirror, and can be used at the same time in the daytime and at night. In addition, the present invention provides an omnidirectional zoom optical system capable of simultaneously measuring the visible and far-infrared regions because the raw material cost is reduced and the manufacturing time is shortened, and the manufacturing cost is reduced by using only four mirrors without using a lens. I can.
