| 4 A common fluorescent dye that absorbs blue light and emits green | 1 This filter passes monochromatic light generated by the sample for visualization |
| 7 This type of filter converts arc light into monochromatic light | 2 Inventor of fluorescence microscopy |
| 3 Fluorescence microscopy eliminated this from the background to produce clear pictures of low concetration targets | |
| 5 This is lost from the light in fluorescein's blue light-green light transaction | |
| 6 This beam splitter reflects the incoming monochromatic light onto the sample while passing the second form of monochromatic light it emits |
