For fluorescence imaging, a custom quad-band filter with external filter wheel (PN: 11536075) with two additional single-band filters (PN: 8118215) were used to image seven dye channels per pass. The filter excitation, dichroic and emission lines are (1) Quad-Band cube: dichroic at 391/32, 479/33, 554/24, 638/31, no excitation or emission filters; (2) external filter wheel position 1: 434/32, position 2: 520/40, position 3: 585/20, position 4: 720/60, position 5: pass-through; (3) single-band 1—585/22 excitation, 594 dichroic, 625/30 emission; (4) single-band 2—635/20 excitation, 647 dichroic, 667/30 emission. |
