Current optical microscope objectives of low magnification have low numerical
aperture and therefore have too little depth resolution and discrimination to
perform well in confocal and nonlinear microscopy. This is a serious limitation
in important areas, including the phenotypic screening of human genes in
transgenic mice by study of embryos undergoing advanced organogenesis. We have
built an optical lens system for 3D imaging of objects up to 6 mm wide and 3 mm
thick with depth resolution of only a few microns instead of the tens of microns
currently attained, allowing sub-cellular detail to be resolved throughout the
volume. We present this lens, called the Mesolens, with performance data and
images from biological specimens including confocal images of whole fixed and
intact fluorescently-stained 12.5-day old mouse embryos.
