碩士 === 逢甲大學 === 資訊電機工程碩士在職專班 === 96 === Radiometer is to be used as infrared formation of image system test station correction and emanation rates of infrared material measurement. This text is discussed with that lens design of far infrared radiometer, The first, It’s necessary to draw up system specification on design process, collect and select appropriate United States of America patent as our system primer structure. According to the system need and use the optics simulate software “Zemax” to make a optimize action to get the best optical performance. The lens acquires finally of infrared zoom lens is compose of six lens, it’s equivalent focal length is 130~450mm, the range of FOV are 8 degree to 26 degree. the Distortion is less than one percentage, On axis of MTF is greater than 0.2 when spatial frequency at 10 lp/mm, Off axis of MTF is greater than 0.4 when spatial frequency at 10 lp/mm, the range of temperature compensate for 20℃ to 60℃. In design process use quality control method--- FMEA (Failure Mode for Effect Analysis) for process control of optic design. It’s including first order design and optimization process and assure of design quality. The zoom lens designs will be applied to the image type radiometer on this thesis.
