Made with MAGIX Système d'illumination Colibri  High-Contrast Images with High Dynamic Range Instead of a traditional white light source, Colibri uses high-performance LEDs (Light Emitting Diodes). Each individual LED delivers a precisely defined spectral range. No undesired light is emitted, so there is no need for suppressing it. With accurate intensity adjustments of the LEDs, Colibri is especially suited for the examination of sensitive living specimens. Designed for simple routine applications to complex applications in Live Cell Imaging: Precise adjustment of intensity for optimum sample protection Fast, microsecond switching times Long life-time LEDs, very economical Stand-alone operation as well as fully integrated in the AxioVision software Use the LEDs separately, sequentially or in  various combinations simultaneously, for example  to search for cells with multiple combinations of  fluorescence markers.
