本研究著重於三波段監視器鏡頭設計，使其可運作於近紅外光波段取得清晰的成像品質，所使用的影像感測器皆可感應可見光至近紅外光波長範圍。此鏡頭可使用在任何時段、任何天候與任何環境上，做可見光至近紅外光波段的監控。 本研究的鏡頭設計，主要針對可見光至近紅外光波段、可見光波段與近紅外光波段下，應用不同的影像感測器所設計出來的鏡組，進行成像品質及公差分析，最後再進行鏡組穿透率分析，讓三波段監視器鏡頭在任何環境下皆可取得較佳的成像品質。 ;This paper focuses on the three-band surveillance lens design, which can operate in the near infrared band to obtain a clear image quality, and the image sensor used can sense the visible light band to near infrared light band. This lens can be used at any time, any weather and any environment, as the surveillance of visible light to near infrared light band. In this paper, the lens design analysis is mainly for visible light to near infrared light band, visible light band and near infrared light band. By applying different image sensors to design a lens group, to analyze the image quality and tolerance, and finally, to analyze the group transmission of the lens, so that the three-band surveillance lens in any environment can obtain a better image quality.
