Laser Scanning Microscopes
Sensitive, Spectral Confocal Imaging and Topography
Confocal laser scanning microscopes use a focused laser beam to scan samples point by point. The ability of confocal microscopy to eliminate out-of-focus light by employing a pinhole aperture results in excellent optical sections with high contrast and enables the high-resolution reconstruction of three-dimensional structures. In the life sciences, confocal microscopes are used to visualize structures within cells and tissues, study dynamic biological processes, and analyze multi-fluorescent samples. In materials science, confocal microscopy is used to examine surface topography, analyze material composition, and investigate the microstructure of materials with high resolution. ZEISS confocal laser scanning microscopes excel with super-resolution imaging down to 90 nm, advanced 4D imaging capabilities, and an unmatched spectral versatility.
