When operating a confocal microscope, or when discussing features and parameters of such a device, we inescapably mention the pinhole and its diameter. This short introductory document is meant to explain the significance of the pinhole for those, who did not want to spend too much time to dig into theory and details of confocal microscopy but wanted to have an idea about the effect of the pinhole.
Multiphoton Microscopy is one of the current hot topics in life science research. The new Leica TCS SP8 DIVE from Leica Microsystems presents a series of beneficial new innovations, including a free tunable non-descanning detector and an ingenious beam manipulating device VBE. The variable beam expander offers free tuning of both beam diameter and axial
