Here we present a new light sheet generator unit for Ultramicroscopy (UM) employing a combination of optical
lenses with aspherical surface structure. UM allows 3D-vizualization of chemically transparent biological specimens
with μm-resolution. Improving optical characteristics parameters of light sheet such as the uniformity factor of
spatial intensity distribution along the line of focus, the thickness of light sheet, and chromatic aberrations are the
most important criteria in this design. Since we do not use any hard edge aperture there is no truncation of the beam
and laser energy is used more efficiently.
Due to these improvements, a marked enhancement in presenting fine details of biological specimens such as
Drosophila melanogaster, entire mouse brain, and hippocampus are achieved.
