With predefined user settings and the option to save personal settings, the system is easy to operate with minimal training. Featuring four lasers for a wide range of applications, the Acousto-Optical Tunable Filter precisely controls laser intensity, minimizes bleaching and reduces photo toxicity on living cells. The Advanced Correction System optics ensure clear images over the full spectral range. The Leica TCS SPE is the only confocal in its class that provides true spectral detection suitable for lambda scan. The Leica TCS SPE provides all the features needed for routine confocal techniques for excellent quality imaging.
