PolyPen is a compact, durable and lightweight device operated by single Turn ON/OFF button and touch screen
(Fig. 1). PolyPen device is optimized for photo-biological applications and easy rapid measurements inside of the
controlled environment as well as outside in the field. It features an innovative user interface with an integral
computer, a full color touch screen display and an in-built light source. The PolyPen is equipped with a non-
destructive leaf-clip sample holder. For data collection and analysis, a comprehensive software package is
provided. PolyPen RP400 can be connected to PC for further data collection and analysis via USB connector.
An integral part of the PolyPen is broad-spectrum internal light source (Xenon incandescent lamp) with radiation
range 380 – 1050 nm. The light beam strikes the sample under the fixed angle of incidence 35° (Fig. 2). The
PolyPen system is optimized particularly for a measurement of planar samples such as leaves. Please note the
variability and reproducibility of the measurement performed with more structured samples like conifer needles
can be affected simply by the geometry of the measurement.
