Not exact matches

Bar - code scanners use Bessel beams because the pencil - like beam of light they produce is thin enough to read between the lines of a bar code; even so, scanner lasers are much thicker than the ones used by Betzig.

Arne Voie, David Burns and Francis Spelman focused a laser beam into a thin sheet to illuminate a fluorescent sample and captured the reflected light using a different objective lens oriented perpendicular to the plane of illumination (i.e. light sheet).

The laser beam is channeled through the illumination lens and creates a thin light sheet that overlaps with the focal plane of the detection lens.
