for Probing of Cells and Tissue in Microbial Mats and Leaves

The MICROFIBER-PAM employs a very thin optical fiber for fluorescence excitation and detection. This narrow fiber permits probing of small spots of heterogeneous photosynthetic surfaces like soil crusts.

Also, placing the microfiber at different penetration depths permits measurements of photosynthetic gradients within microbial mats and leaves.
