LONG WAVELENGTH INFRARED OPTICAL ZOOM LENS SYSTEM WITH HIGH MAGNIFICATION

摘要

The present invention relates to a high magnification continuous zoom far infrared ray optical system, and more particularly, to a high magnification continuous zoom far infrared ray optical system, which comprises an objective lens which is opposite to an object and receives far infrared rays of the object, And a magnification lens, a fixed lens, a compensation lens, and an imaging lens are arranged in this order along the direction of the rear side optical axis of the objective lens, wherein the magnification lens moves along the optical axis direction to change the magnification of the image, The lens moves along the optical axis and corrects a defocus caused by a change in the distance of the object and a temperature change. The imaging lens forms an image received by the objective lens, and is located along the direction of the rear optical axis of the imaging lens And a far-infrared ray noncooling detector for converting an image formed by the imaging lens into a digital image signal and outputting the digital image signal.;
