摘要
介绍了一种三组元联动机械补偿式小型化中波红外连续变焦光学系统。针对阵列规模640×512,像元尺寸15μm的中波制冷型红外探测器,设计了焦距20~275 mm, F数5.5的连续变焦光学系统,系统长度90.6 mm。具有变倍比大、结构紧凑、元件数量少的特点,适合应用于小型化的机载光电吊舱系统以及轻量手持红外望远系统中。
In this paper,a miniaturized middle wavelength infrared optical system is proposed,which is based on a three-component linkage continuous zoom.An F number 5.5 middle-wave infrared zoom lens with 20~275 mm focal length is designed for cooled MWIR detectors with 640×512 array size and 15μm pixel size.The total optical length of the system is 90.6 mm.The system has the characteristics of large zoom ratio,compact structure and less components.The designed system is suitable for applications in miniaturized pods systems,lightweight handheld infrared telescope systems.
