Abstract
A crystal for flow cytometry with dual laser beams is disclosed. The crystal is a birefringent crystal comprising a material composition including a quartz mineral having a face side including a face angle of ninety degrees plus or minus one tenth of a degree; a wedge side that is substantially perpendicular to the face side, wherein the wedge side includes a wedge angle of two degrees plus or minus one tenth of a degree; and a major side that is substantially perpendicular to the face side and the wedge side. The major side includes a thickness of one and one-half millimeter plus or minus one tenth of a millimeter. A polarized light beam entering the birefringent crystal at an incident angle is separated into an ordinary light beam and an extraordinary light beam.
