To join, leave or search the confocal microscopy listserv, go to: http://lists.umn.edu/cgi-bin/wa?A0=confocalmicroscopy ***** Dear colleagues... (Sorry if you are getting this message second time, I am having some trouble sending to the Confocal List) I was at the Microscience meeting in London in 2008, and in one vendor booth they were telling (not really displaying because they didn't have it with them) about a strange microscope that achieves a very good resolution in transmission, better than the diffraction limit, and a large depth of field. They didn't explain how it works. I think the company was based in Germany, but I don't remember the name. Does anyone know what it could have been or the company name? I would like to contact them. Thanks! Mike Model Kent State University |

To join, leave or search the confocal microscopy listserv, go to: http://lists.umn.edu/cgi-bin/wa?A0=confocalmicroscopy ***** Hi, Mike I'm not sure about the one at the Microscience meeting, but there is an interesting holographic microscope which is just now coming out of Canada ... and I know that they've already installed one at the U of Heidleberg in Germany. It is the DIHM (Digital In-situ Holographic Microscope). The company is Resolution Optics (ResolutionOptics.com). It not only has a great DOF, it can track motion in 3D and is available in both a desktop model and a retrofittable system based on an objective (objective, point source, software that works with a set of staging and camera options). They also have a submersible version that works down to depths of 5 km (3miles!). I saw them at M&M. Their CEO Is Stefan Jericho ([hidden email]) Hope this was helpful, Barbara Foster, President and Sr. Consultant Microscopy/Microscopy Education 7101 Royal Glen Trail, Suite A McKinney TX 75070 P: (972)924-5310 Skype: fostermme W: www.MicroscopyEducation.com NEWS!

To join, leave or search the confocal microscopy listserv, go to: http://lists.umn.edu/cgi-bin/wa?A0=confocalmicroscopy ***** Was it the Richardson Technologies instrument? This appeared to resolve unstained mitochondria through the transmitted light path. Not sure that it could collect a large depth of field and also thought it was 2004 or 2006 that they were present. Phase Focus is a different system again that can 'virtual' focus through z once a x,y tile has been collected. This system uses coherent light and collects the light in the transmission light path.

I remember they were saying that it was based on some principle that had never been published or patented. I also think (though not 100% certain) that it worked in all the common transmission modes. But all they had was a brochure.. -----Original Message----- From: Confocal Microscopy List [mailto:[hidden email]] On Behalf Of Judy Trogadis Sent: Monday, October 04, 2010 9:22 AM To: [hidden email] Subject: Re: Mystery microscope ***** To join, leave or search the confocal microscopy listserv, go to: http://lists.umn.edu/cgi-bin/wa?A0=confocalmicroscopy ***** Yes, it does sound like the Richardson microscope. It has no oculars. They also used an oil coupled condensor. Dr. Richardson sold the company and the patents to someone else. I can try to find out who is selling them now, I know one of their ex-employees.

This appeared to resolve unstained mitochondria through the transmitted light path. Not sure that it could collect a large depth of field and also thought it was 2004 or 2006 that they were present. Phase Focus is a different system again that can 'virtual' focus through z once a x,y tile has been collected. This system uses coherent light and collects the light in the transmission light path.

To join, leave or search the confocal microscopy listserv, go to: http://lists.umn.edu/cgi-bin/wa?A0=confocalmicroscopy ***** Good afternoon, there have been a number of important answers to Dr. Model's question. I allow myself to recommend for those interested in history, also in how developments can follow strange, perhaps personally tragic, paths, to do a search on the internet on "Royal Raymond Rife". I beg your pardon if this hint has been provided any earlier and thus would be "old news". Best wishes, Johannes -- P. Johannes Helm, M.Sc.

From http://www.grayfieldoptical.com/faq.html "Although the exact working principle is a trade secret, ..." After this, there is some hand-waving markteting talk. I can't really comment on the images of those test slides and diatomes on the web page, but from the images of cells they show, I am not impressed. Doesn't look like 100 nm resolution to me. see Grayfield homepage or http://www.mikroskop-olbrich.de/ergonom_4000.html There is also a movie at http://video.google.de/videoplay?docid=839679424840450517# Microscopy starts at ~4:10. This movie apparently also explains the real cause of cancer, I didn't watch all of it, though, it's 48 minutes. More videos at http://www.grayfieldoptical.com/online_videos.html Other than that, the "Institut f. Interdisziplinäre Grundlagenforschung Kurt Olbrich" can be googled as a reference for confirming the effect of various "water vitalising" procedures on German web pages. http://www.boehm-egger.de/produkte_prufungen.htm http://www.theta-reiki.de/trinkwasser/die-loesung/ http://www.aquavitera.de/wasserbelebung-pejosan-wasservitalisierung-schauberger-wasserwirbler-aquavitera-wasserveredler/wasserveredler-pejosan-petit-.119.155.de.html The subject of this thread seems to be quite fitting, in retrospect.

Why should the 100nm resolution version cost so much more? Maybe just so that people don't buy it and so won't find out that it doesn't work? There are several 100nm (or better) optical resolution microscopes you can buy based on well published and dependable principles. (Structured illumination, STED, 4pi, stochastic single molecule imaging.) There are also microscopes with extended depth of field (but no lateral super-resolution). Carol Cogswell was among those working in this field.

A soluble molecule rather than a membrane probe. A small amount of background in cytosol or other organelles could be managed. Many thanks, Tobias Baskin -- _ ____ __ ____ / \ / / \ / \ \ Tobias I.

I recall that Hartmut Quader showed some pretty nice movies of plant ER dynamics using DiOC6 (which I know, doesn't meet your non-membrane probe criteria). I seem to recall hearing that the same method doesn't necessarily work in animal cells. If I might ask, what is your rationale for needing a label specifically for the lumen of the ER?

They may not be on this list, they've just submitted a ms. on cell-cell transport via the ER lumen, but not sure exactly what they used or how they got it into the ER except by microinjection. cheers, Rosemary On 7/10/10 7:33 AM, "Tobias Baskin" <[hidden email]> wrote: > ***** > To join, leave or search the confocal microscopy listserv, go to: > http://lists.umn.edu/cgi-bin/wa?A0=confocalmicroscopy > ***** > > Hi microscopists, > Anyone know of a way to load a small (say less than 1 > kDa) fluorescent molecule into the ER lumen?
