PolyPen RP 410手持式植物光譜測量儀通過內部光源（氙氣白熾燈380-1050nm）測定植物葉片的反射光譜，也可以測定其他光源的透光度和吸光率。PolyPen在軟件中內置了幾乎所有常用的植物反射光譜指數公式，例如NDVI，PRI，NDGI等。測得的數據以圖形或數據表的形式實時顯示在儀器的顯示屏上。這些數據都可以儲存在儀器的內存里并傳輸到電腦里.

 內置植被指數：

PolyPen RP 410 UVIS：NDVI、SR、綠度指數、MCARI、TCARI、TVI、ZMI、SRPI、NPQI、PRI、NPCI、Carter指數、SIPI、GM1。

PolyPen RP 410 NIR：NDVI、SR、MCARI1、OSAVI、MCARI、TCARI、ZMI、Ctr2、GM2
