PolyPen RP 410 NIR

Key Features and Functionality

• Spectral Reflectance Measurement: The PolyPen RP 410 incorporates an internal Xenon incandescent lamp to emit light (380 to 1050 nm) and measures the spectral reflectance off a leaf’s surface.

• Automatic Index Calculation: The device’s firmware automatically calculates a wide array of commonly used reflectance indices (vegetation and stress indices), such as:

  • Normalized Difference Vegetation Index (NDVI): NDVI = (R_{NIR} – R_{RED}) / (R_{NIR} + R_{RED})

  • Photochemical Reflectance Index (PRI)

  • Normalized Pigment Chlorophyll Index (NPCI)

  • …and many others (e.g., Simple Ratio Index, Anthocyanin Reflectance Indices, Carter Indices).

• Stress Detection: By monitoring changes in pigment content (like a decrease in chlorophyll or an increase in flavonoids/anthocyanins), the device can detect nutrient deficiencies or drought stress in plants long before symptoms are visible to the naked eye.

• Customization: It allows for the calculation of custom-defined indices, enabling specialized research applications.
