6400-02B Red/Blue LED Light Source

6400-02B LED Light Source

The 6400-02B LED source is designed with red and blue LEDs (665 and 470 nm, respectively) to provide uniform intensities up to full sunlight (~2,000 µmol m-2 s-1) over an area of 6 cm2. Mounting simply requires replacement of the upper half of the standard leaf chamber. Powered from the LI-6400XT console, the 02B allows the light intensity to be automatically controlled, which is especially critical for response curve measurements.

The 6400-40 Leaf Chamber Fluorometer enables the simultaneous measurement of chlorophyll fluorescence and gas exchange over the same leaf area. The 6400-40 is designed with a uniform, integrated LED light source and PAM fluorometer that easily attaches to the LI-6400XT sensor head, giving the user complete control of the environment surrounding the 2 cm2 leaf area. Measurements of combined gas exchange and fluorescence expand the LI-6400XT's usefulness in assessing a plant's response to stress (read more).
