Leaf Chamber FluorCam has all the imaging features of the other instruments of the FluorCam family, but it is designed for attachment to a leaf gas exchange chamber. Thus, the chlorophyll fluorescence imaging can be performed at the same time as the gas exchange measurements. A great advantage of the Leaf Chamber FluorCam is that the leaf chamber can be used to control precisely the environment of the sample, e.g., with respect to temperature, relative humidity and the partial pressure of various gasses that influence photosynthesis and transpiration (CO2, O2, water vapor).
The Leaf Chamber FluorCam may be attached to standard chambers provided by manufacturers of leaf gas exchange systems, such as ADC or PP Systems. Fluorescence emission is induced by sets of super-bright orange (blue) LEDs that provide measuring flashes. The photochemistry is driven by orange (blue) continuous actinic light and/or strong pulses of actinic light. The FluorCam software automatically generates sequences of fluorescence images for easy visualization of photosynthetic differences between and within samples. Values are also presented numerically.
