description Se proporcionan un citómetro de flujo, su conjunto de óptica láser y métodos para ensamblarlo. El citómetro de flujo es capaz de producir resultados consistentes y precisos a pesar de la exposición a condiciones ambientales adversas tales como, por ejemplo, cambios de temperatura dentro de un rango de temperatura relativamente amplio y/o una cantidad relativamente grande de vibración mecánica de eje aleatorio. El citómetro de flujo de la presente divulgación es adicional o alternativamente relativamente insensible a los cambios reales o aparentes de la corriente central, emplea un haz que converge lentamente a lo largo del eje perpendicular al flujo de la corriente central y proporciona la capacidad de medir con precisión el tiempo de vuelo. (Traducción automática con Google Translate, sin valor legal) A flow cytometer is disclosed. It comprises a flow cell defining a flow direction; a collimation assembly including laser diode and a collimating lens configured to produce a laser beam along an axis; a positive cylindrical lens disposed on the axis configured to receive the laser beam from the collimation assembly; and a negative cylindrical lens disposed on the axis and configured to receive the laser beam from the positive cylindrical lens. A cylindrical objective lens is disposed on the axis and is configured to receive the laser beam from the negative cylindrical lens and project the laser beam onto the flow cell such that the laser beam incident on the flow cell defines a first beam waist 1/e2 diameter in a direction parallel to the flow direction of the flow cell of 6.7 µm to 9 µm and a second beam 1/e2 diameter in a direction perpendicular to the flow direction of the flow cell of 190 µm to 210 µm.
