The Colibri Light Emitting Diode (LED) is a light source for fluorescence microscopy. The intensity of the narrow-band LEDs can be quickly and accurately set for any wavelength and exactly adapted to the specimen. As the switching procedure is purely opto-electronic, there is no motion or vibration that could impair image quality in high speed time series experiments. It is possible to switch excitation wavelengths in micro seconds. Minimized heat build-up alos stabilizes conditions during experiments. A selection of four LEDs can be used individually, sequentially or simultaneously with any intensity setting.
