Paper Abstract

Resonant two photon excitation of UV absorbing dyes with red light is a new concept in 3D microscopy. This technique provides functionality which is virtually equivalent to a confocal microscope. Two photon excitation allows excitation of UV dyes without special UV corrected optics. Resonant two photon excitation in microscopy, as known until now, utilizes expensive, high powered pulsed femto- or picosecond lasers. In this paper a cost effective alternative to resonant two photon is presented.
