The extremely high sensitivity of the camera allows accurate measurements at the subcellular level.
Customized Fluorescence Imaging Systems We can provide chlorophyll fluorescence imaging systems for large scale screening in the laboratory and field, or for 3-dimensional studies. Moving FluorCam systems can be designed and built to your specifications for the study of large plants (e.g. corn) or for analysis of multiple samples in large growth trays. Systems can be built in open configurations (as in examples shown opposite), or enclosed in a cabinet for more convenient control of dark adaptation and actinic light. If required, an additional camera can be used for true-color analysis. Please contact us for details. We are happy to consult with you concerning your exact requirements and to provide designs without obligation.
