Product introduction
Portable/chlorophyll fluorescence imager HXIN-PSIMAGE100 can be used not only for chlorophyll fluorescence imaging, but also for imaging and analyzing the heterogeneity of green fluorescent protein (GFP) distribution in plants, animals, their tissues and colonies. In this system, four groups of high-brightness light emitting diodes provide high-intensity measurement light or moderate sustainable light, and the high-intensity measurement light pulse can make the imaging measurement of fluorescence signal carry out under high background light. Fluorescence signals are detected and imaged by high sensitivity CCD camera, and dynamic fluorescence images can be analyzed by attached software.
