    Multiphoton Microscopy – a Satisfied Wish List

    The colorful picture shows colon tumor cells, fluorescently labelled and lineage traced from a multicolor tracer. The gray color codes for the second harmonic generation (SHG) signal from Collagen 1. Lineage traced tumor cells are shown in magenta, blue, green, yellow and red. All channels were recorded with two-photon excitation, using the SP8 DIVE by Leica Microsystems. Sample and image were kindly provided by J. van Rheenen, H. Snippert, Utrecht (the Nederlands,) and I. Steinmetz, Leica Microsystems Mannheim.

    Mission Impossible Accomplished: Tunable Colors for Non-descanning Detection

    Leica Microsystems’ 4Tune detector, the key component of the SP8 DIVE Deep In Vivo Explorer, provides spectrally tunable image recording with non-descanning detection. An innovative solution for multiparameter multiphoton microscopy. The colorful image on the right shows multiphoton microscopy of an unstained mouse skin section acquired using the 4Tune detector. The green color codes for autofluorescence of muscle tissue. Red shows second harmonic generation of fibers upon illumination with 900 nm. The blue pattern is generated by third harmonic generation at lipid boundaries from illumination at 1230 nm.

    Laser Beam Shaping for Multicolor Multiphoton Microscopy

    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 freely tunable non-descanning detector and an ingenious beam manipulating device VBE. The variable beam expander offers free tuning of both beam diameter and axial IR-correction for up to four IR beams simultaneously.

    Five Questions Asked: Prof. Dr. Jacco van Rheenen speaks about the most important considerations when imaging deep into mouse tissue

    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.
