Optical Filter Banks
PMTs and associated mirrors and filters are organized into banks that are grouped by excitation
source — each optical fiber directs light to a particular bank, as shown in the next figure.
The ZE5 Cell Analyzer can be configured with up to five banks, one for each laser. The five banks are
grouped into three regions: A, B, and C. Region A, located on the bottom, consists as a single bank,
while regions B and C, located on the top left and top right, respectively, each contain two banks of
PMTs.
