#Happycustomer: Maurizio Chiccioli at @Yale just announced the installation of our White Dwarf 3P in his lab. It will be used for #intravital (#invivo) deep tissue #imaging. Our high-power #femtosecondlasers for #bioimaging are gaining increasing importance beyond #neuroscience.
building-up...exciting imaging coming soon! @Class5Photonics @Thorlabs
