UN-COOLED THERMAL IMAGING CAMERA amp;times;6 MAGNIFICATION CONTINUOUS ZOOM OPTICAL SYSTEM

摘要

A non-cooled thermal imaging camera ×6 magnification continuous zoom optical system according to the present invention comprises; an objective lens which is opposed to an object and receives far-infrared rays of the object to capture an image; and a magnification lens, a compensation lens, a fixed lens, and an image forming lens which are sequentially arranged in a rear optical axis direction of the objective lens. The magnification lens moves in an optical axis direction to change the magnification of the image. The compensation lens moves along an optical axis and corrects a defocus occurring at a time of a distance change and a temperature change of the object. The imaging lens forms an image received by the objective lens. A far-infrared ray non-cooling detector is located in a rear optical axis direction of the image forming lens, converts the image formed by the image forming lens into a digital image signal, and outputs the signal. In the optical system, an F-number is 1.4 and an effective focal length is 25 to 150 mm.;COPYRIGHT KIPO 2016
