MAXI Version


The MAXI version of the IMAGING-PAM M-Series employs a very compact and powerful 300 W LED array for homogeneous illumination of up to 10 x 13 cm areas (microtiter plates) with pulse-modulated excitation, actinic light and saturation pulses.

Two different CCD-cameras are available. For high sensitivity applications the IMAG-K6 (2/3" chip, 1392 x 1040 pixels with 4-pixel-binning) is recommended. For standard applications the IMAG-K7 (1/2" chip, 640 x 480 pixel) is available, which can be used in conjunction with the powerful K7-MAX/Z zoom objective (F1.0/f=8-48mm). So the system features an imaged area from 10 x 13 cm stageless down to 13 x 22 mm at constant resolution.

A special Mounting Stand with Eye Protection is provided (IMAG-MAX/GS), which features a red perspex glass hood, through which the red chlorophyll fluorescence can be observed. On the bottom of the Mounting Stand IMAG-MAX/GS an x-y stage for variable sample positioning or a multiwell plate can be placed at defined working distance of 18.5 cm.

The bottom plate can be removed so that the whole stand can be jacked up (legs provided) for imaging of plants growing on trays or in pots – additionally the combination with the large gas exchange cuvette 3010-GWK1 for the GFS-3000 is possible using optional adapter sets.


Configurations of the MAXI Version
