The etching on the Ibidi coverslips seems more clear and also shows up in most fluorescence channels, which is helpful, but they are only made in 28 mm round diameter, which is wider than a standard slide and may not work with all types of stage inserts (assuming that you're mounting the coverslip on a slide). Of note, both of these options are labeled so that you can reproducibly find locations (e.g., the cells in grid C7, F5, etc.). We have used these for comparing single cell imaging results between multiple systems.

May I have your kind advice on the tolerance of the chromatic aberration of such a system? And for airyscan confocal, is there a better tool than tetrabeads for the evaluation of system performance, in terms of its super resolution (FWHM measurement) as well as chromatic aberration?

Some web links are: new Olympus X-Line objective lenses, for example the teaser page, https://www.olympus-lifescience.com/en/landing/x-line/ See online and/or local representatives, for more info on X-Line, most are corrected (see O' content for details) for 400-1000 nm, a couple to ~450 - ~650 nm. You can also discuss microscope aberrations with the local representatives of Zeiss with respect to AiryScan (1) and AiryScan 2, and whatever other confocal and super duper resolution microscopes you have. See Brown & Cole led papers, especially PubMed hits #3 and #4, https://www.ncbi.nlm.nih.gov/pubmed/?term=brown+c+cole+r // Not just the objective lenses are in play, for good and/or bad. I had never paid much attention to this one: Zeiss does some correction(s) in the tube lens, whereas the other major microscope companies do all their corrections in the objective lens. So: how good is the Zeiss tube lens? Has Zeiss changed (improved? cheapened?) the tube lens in the 'couple of decades' since it would have been introduced with their 'infinity' corrected objective lenses? With respect to some or all of the vendors, any glass in the epi-illumination path could also impact the excitation side quality of widefield fluorescence (and reflection) microscopes. enjoy, George On 8/10/2019 6:40 PM, Tong Yan wrote: > Dear George, > > Thank you very much for the resourceful information. > > One more thing about the confocal system evaluation is the chromatic aberration.

They may have improved since then. For PSF measurements, we found that 80 nm gold beads are much more convenient than fluorescent beads: no bleaching and much brighter signals to start with (DOI:10.1017/S1431927619000060 <https://doi.org/10.1017/S1431927619000060>). Your instrument must allow reflection confocal microscopy. With simple confocals using glass filters as dichroics this is usually not a problem since the dichroic will let pass enough of the 'excitation' light. You have to be able to take out the detection filter or set you spectral scanning unit to the 'excitation' wavelength. Obviously, if you do the reflection PSF for several wavelengths, you also can check for chromatic aberration. Strictly speaking your fluorescent channels will be a little bit different, since the detection wavelength is a few dozens nm longer than the reflection. As for expected results, Leica made a huge point that their 100x STED white objective has a chromatic aberration of less than 50 nm in z. In conclusion, 'normal' objectives will have considerably more. I would expect up to a few 100 nm in z for NA 1.4 objectives and more for smaller NAs. In that context let me add that we found that the immersion oil also may have a considerable impact on the chromatic aberration. I'd suggest to only use the oil recommended by the manufacturer of the system. Or else test for chromatic aberration (and resolution).
