Z200 FluorCam – Open

The Z200 Open- FluorCam System is a highly modular instrument for chlorophyll fluorescence imaging of plants, plant tissues and algae.  The system is composed of 4 LED light panels, CCD camera and controller, adjustable frame and software with a PC computer. This system is available in standard 10×10 and 20×20  imaging areas.

The LED panels and the light source generating saturating flashes can be arranged at various angles and distances from the sample.  The position of the camera may also be adjusted for added precision.  The maximum area for imaging with standard hardware is 10 x 10 cm, or 20 x 20 cm, depending on the size of selected light sources.  Much larger areas, up to 200 x 100 cm, can be imaged by the addition of LED panels and/or by mounting the whole system on a movable frame. Please  Contact Qubit for further details.
