Selectable confocality

The confocal mode of the LS series of laser scanners provides better background suppression and also better discrimination between bright and dark signals (contrast, intrascenic dynamic range) in the sample. The LS Series Laser Scanner offers three user-selectable pinhole sizes, which give the user three grades of more or less confocal measurements. While handling samples of considerable optical depth (e.g. flow-through chips, gels) or warped surfaces, the instrument can be easily switched from confocal to non-confocal mode.
