13. Resolution vs Contrast: Diatom test

14. Overview: Gyrosigma balticum (diatom), 63x/0.80 NA objective, bright-field Test of resolution of surface frustules on Gyrosigma Slide by Klaus Kemp Zeiss Axioskop, Zeiss Axiocam CCD black and white images

15. Resolution and contrast: NA = 0.9 (condenser aperture wide open) Image well-resolved, but somewhat lacking in contrast

16. Resolution and contrast: NA = 0.8 (resoution of condenser matches that of objective) Image well-resolved and with good contrast

17. Resolution and contrast: NA = 0.4 (condenser diaphragm at 50% field of view in back focal plane) Image poorly resolved – Airy disk size is such that individual frustules blend together and give the false image of ridges on diatom surface. (“Bad” image)

18. Resolution and contrast: NA = 0.05 (condenser diaphragm stopped down to smallest aperture) Image very poorly resolved – Airy disks so large that many points in image run together and there is little resolution. (“Bad” image)

31. Unknowns

33. Extra credit and other overlapping stuff

34. Make your own slide: all slides were made by me unless otherwise noted. This would constiute at least half the slides presented here. Dark-field: Several, including two darkfield images of morel asci (in both Zoom and Story projects) and one of the aphid images. “Bad” images: two of the diatom slides. Problems with the darkfield aphid slide are also noted.
