應用案例 1：
歐盟委員會聯合研究中心通過無人機遙測技術研究葉緣焦枯病菌在橄欖樹中的感染。同時通過FluorPen葉綠素熒光儀和RP400光譜儀直接檢測葉片的葉綠素熒光和反射光譜植被指數，用于對照修正無人機遙測數據。研究結果發表在《Nature Plants》（Zarco-Tejada，2018）。
應用案例 2：
水稻灌漿期的夜間高溫會顯著影響水稻的產量。捷克科學院研究中心與水稻研究所合作研究夜間高溫對成熟水稻穗光學特性的變化追蹤。研究者使用FluorPen手持式葉綠素熒光儀測量了光合系統有效光化學效率ΦII（也稱為有效量子產額QY或ΦPSII）和穩態熒光Fs。同時使用PolyPen手持式植物反射光譜測量儀的前期型號WinePen測量了反射光譜曲線，并計算了PRI、mSR705、mND705、R470/R570、R520/R675等9項植被指數。這些植被指數與水稻葉片/穗的光合能力、穩態熒光、葉綠素濃度等緊密相關（Gil-Ortiz R et al. 2020）。
