The EVOS fl digital imaging system includes a microscope, high-resolution digital camera, and an LCD. An LED-based "light cube" combines an illumination source, light engine, and fluorescence filters into a single compact unit, eliminating the need for users to align or calibrate the device. Users can adjust the LEDs, reducing the chance of photobleaching or phototoxicity. The EVOS fl includes an embedded microprocessor, giving users full control of image acquisition and management without the need for an external computer.
