Figure Lengend Snippet: Schematic diagram of our in-house made optical tweezers. LD785nm is a laser diode, LP1 first linear polarizer, QWP quarter-wave plate, VHWR vortex half-wave retarder, LP2 second linear polarizer, M mirror, DBS dichroic beam splitter, OL 40x objective lens, L1 condenser lens, lamp white light lamp, F fluorescence filter, L2 convex lens, and CCD the CCD camera.
Article Snippet: The generated vortex beam was then directed through a dichroic beam splitter (DBS) cube (69-902, Edmund optics) and focused onto the sample plane using an 40x objective lens (OL).
