With narrow spectral profiles at each wavelength and precise control of intensity in 1% increments, specimens are protected from overexposure at the undesired wavelengths and high intensities typical of wide spectrum sources. The system can be configured using LEDs with peak wavelengths at 400, 445, 465, 505, 525, 595, and 635nm wavelengths. The light it provides is stable, controllable, and thermally cooled, making it ideal for live cell imaging, photobleaching, fast switching, multiple probe staining, and time-lapse imaging.
