PolyPen RP 410手持式植物光谱测量仪通过内部光源（氙气白炽灯380-1050nm）测定植物叶片的反射光谱，也可以测定其他光源的透光度和吸光率。PolyPen在软件中内置了几乎所有常用的植物反射光谱指数公式，例如NDVI，PRI，NDGI等。测得的数据以图形或数据表的形式实时显示在仪器的显示屏上。这些数据都可以储存在仪器的内存里并传输到电脑里.

 内置植被指数：

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

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