Abstract:
1. A flow cytometer comprising: a light applying section configured to apply laser light to a sample flowing in a channel; and a fluorescence detecting section configured to detect fluorescence generated from said sample irradiated with said laser light; said fluorescence detecting section including a multichannel photomultiplier tube having a plurality of detection channels capable of simultaneously detecting a plurality of light beams generated by the sample, a light separator configured to separate said fluorescence according to wavelengths to provide said plurality of light beams generated by the sample, said light separator being provided by a transmission grating or a prism, and a telecentric condenser lens configured to receive said plurality of light beams generated by the sample from said light separator and direct said plurality of light beams toward said plurality of detection channels of said multichannel photomultiplier tube so that the optical axes of said plurality of light beams are parallel to each other.
