http://listserv.acsu.buffalo.edu/cgi-bin/wa?S1=confocal Dear all, one of my customers asked me the question about what was the first commercial single point scanner. I was much tempted to answer straight away with "Biorad", but the longer I think about it the more I am in doubt. At that time I was in my (microscopic) larvae stage and I am not sure to have the time scale right. And I would like to give the correct answer unbiased by company or geographic issues. Your input would be much appreciated Boris ___________________________________________________ Boris Zarda Dr. rer. nat.

http://listserv.acsu.buffalo.edu/cgi-bin/wa?S1=confocal I'm sure you are right about the Bio-Rad in principle, but it wasn't the well-known MRC 500, but the very different SOM 100. In fact so far as I can find out the first microscope advertised for sale was by Oxford Optoelectronics but I believe that before the first one was delivered the design had been taken over by a company called Dubilier, who were thus the first to actually sell one. Dubilier was then bought by Polaron who in turn were taken over by Bio-Rad. The SOM 100 was a stage-scanning machine using a He-Ne laser and was intended for reflection imaging, so it found little use in biology. Bio-Rad soon dumped it in favour of Brad Amos' MRC design, which had biological imaging as its first priority. This caused some grief to the Oxford team who had developed the SOM - and just to rub salt into the wound it was a design from Cambridge which supplanted it!

http://listserv.acsu.buffalo.edu/cgi-bin/wa?S1=confocal I have in front of me an advert for the SOM 100 Lasersharp from Bio-Rad (Polaron Division). Some names persisted a long time! This was early 1987 - the MRC 500 was launched later that year. This was the Oxford design from Colin Sheppard and Tony Wilson, which had been on the market on a small scale for a few years before that. Both Sarastro (Kjell Carlsson's design), later to be Molecular Dynamics, and Heidelberg Instruments (later to become part of Leica) were not far behind.

http://listserv.acsu.buffalo.edu/cgi-bin/wa?S1=confocal Guy et al-- I think that prior to either of these, there was a non-laser scanning instrument featuring a single eyepiece (!) and probably the least ergonomic design of any microscope. It was made by a company in Wisconsin, USA, but unfortunately I can no longer remember the name! However, I do remember that they got the cover of Science in (if I'm correct) 1986 showing a picture of a Golgi-stained cerebellar Purkinje cell.

http://listserv.acsu.buffalo.edu/cgi-bin/wa?S1=confocal Yes, but that was a spinning-disk system. The query was about point scanners. Mojimir Petran's 'Tandem Scanning Microscope' was made in small numbers by a tractor maker (!) in Czechoslovakia. I believe Alan Boyde was the first customer. It had, as you say, a single vertical eyepiece. Tracor-Northern in Madison (now Thermo Noran, I think) took out a licence and soon added a proper binocular head (not really hard to do). It was supported by their TN 8502 Image Analysis system and you could do some quite neat things with the combination, like taking a stereo pair without needing to acquire an image stack. Mind you, last time I used a modern Perkin Elmer spinning disk system the eyepiece for the direct ocular view was still single and very inconvenient! I guess they don't think people will use it.

http://listserv.acsu.buffalo.edu/cgi-bin/wa?S1=confocal Hey if one stick to laser (point) scanning I'd say 1)BioRad; 2)Sarastro; 3)Leica in order of appearance. With BioRad being one generation ahead of the others. I actually saw the fisrt prototype of the MRC 500 in Brad Amos's lab who was still using it back in '91.

Hi, Martin
Was that Meridian? If so, it was an interesting instrument because in addition to doing confocal imaging it did laser ablation. They sold a special form of growth medium that was especially sensitive to one of the laser lines. It enabled you to grow cells in culture then either "zap" cells that you did not want to see or to cut out "islands" of cells that you wanted to harvest/view. By the way, the first single point laser scanner I remember is also the SOM. I remember collecting a short file on it while working at Cambridge Instruments around 1986-87.

http://listserv.acsu.buffalo.edu/cgi-bin/wa?S1=confocal Dear, As far as my memory is correct we recieved the first commercial MRC500 confocal in Europe. Feb 1988. At that time some prototypes of Leica were also displayed in EMBL. The EMBL system even had no possibility to use conventional object observation and hence you needed a rather blind imaging. Quite difficult if you have to look and search your object with alone confocal illumination and slowscanning. Andrew Dixon, was than the most important person at BIORAD, probably he has some exact dates. As they told me the MRC500 was presented to the public in dec 1987 at the american cell biology meeting. Am I correct?

http://listserv.acsu.buffalo.edu/cgi-bin/wa?S1=confocal We had this discussion in this list 9 years ago and I said then that the SOM 100 was on sale a year before the Sarastro Phoibos, and the Oxford Optoelectronics / Dubilier machine was on sale well before that (obviously, since it was the predecessor of the SOM). According to the Encyclopedia of Optical Engineering By Ronald G. Driggers "the first commercial confocal microscope was launched by Oxford Optoelectronics in 1982". This is well before Sarastro had even filed their patents. In an historical review, Biology of the Cell 95, 335-342 (2003) Brad Amos and JG White describe the Kjell Carlsson's Sarastro Phoibos as appearing at the same time as their MRC 500.

Dear All,
I got to know some more history from Colin (who was instrumental in establishing Oxford optoelectronics). It turns out that the first commercial point scanning confocal was prototyped ca. 1975 in Oxford which eventually became SOM-25. SOM-100 was preceded by SOM-25. They sold couple of them to semiconductor developers (texas instruments and perhaps intel) that were interested in studying surface defects. On the list there was discussion about origin of the term 'confocal' sometime back. These interesting chronological details transpired during our discussion... 1940: Goldman used slit to obtain 'sections' in opthalmic scope... It also employed idea of illuminationg and detecting the signal at different angles (termed angular gating) to get rid of stray light (a la dark-field ?!) (Goldman H., Spaltlampenphotographie undphotometrie. Opthalmologica 98, 257-270) 1943: Z Koana from University of Tokyo publishes (in Japanese) idea of point illumination and point detection using lamp+pin-hole and photodetector+pin-hole. Pin-holes were meant to get rid of stray light during spectrophotometry. 1955: Hiroto Naora (Koana's junior collegue) publishes results based on this method...(H. Naora, Microspectrophotometry of cell nucleus stained by Feulgen reaction I. Microspectrophotometric apparatus without Schwarzschild-Villiger effect, <a href="javascript:AL_get(this, 'jour', 'Exp Cell Res.');">Exp Cell Res. 1955 Apr;8(2):259-78.) The S-V effect dealt with in this paper is stray reflections. Fig.3 of this paper (at http://www.sciencedirect.com/science?_ob=ArticleURL&_udi=B6WFC-4DYV56H-26&_user=10&_coverDate=12%2F31%2F1955&_rdoc=1&_fmt=&_orig=search&_sort=d&view=c&_acct=C000050221&_version=1&_urlVersion=0&_userid=10&md5=72a34fa8ece505094e6000c56a87de82 ) shows the apparatus. 1957: Marvin Minsky's patent (Very similar to Koana-Naora instrument in terms of point illumination and point detection) 1975: Oxford optoelectronics established 1977: First use of term 'confocal' in journal article...CJR Sheppard, A Choudhury, Optica Acta, 24, 1051-1073 (1977)..which as Guy had pointed out earlier was earlier called Type-2 scanning optical microscope..

A couple of footnotes to Shalin's
timeline:
Nobody really seemed to know what had happened to Hiroto
Naora
since that pioneering work - and then we discovered that he
was
working (at an age when most of us would be retired) at the
Australian National University in Canberra. So he
gave an
invited talk on his work at the 2000 Australian
Microscopy
conference in Canberra. It was absolutely fascinating
and one
can only wonder at the difficulties he must have faced
doing
such work in immediately post-war Japan. Colin and I
talked to
him afterwards and he was very definite that it was his
research,
and Koana was just his supervisor.
I have a micrograph I use in my lectures which shows the
Schwarzschild-
Villiger effect rather well - in a bright-field
fluorescence image of a leaf
you can also see the (non-fluorescent) cell walls by the
light they scatter
from the fluorescent chloroplasts - in the confocal they
are (of course)
not seen. People often forget that this is an
additional benefit of confocal
imaging.
Some years back I was involved in a lengthy email exchange
with Marvin
Minsky on historical aspects of confocal, in particular
patent issues. Then
I asked him if he was aware of Naora's work (which was,
after all, published
in leading US journals). I never heard another word
from Marvin.

Quite correct. But their LSM44 was not the first
non-confocal scanning
optical microscope. That goes back much earlier to
1950 (prototype)
and 1953 (commercial). Nevertheless it was obviously
a very useful
background for Zeiss to develop their first confocal.
However the LSM10
was not very good. The hardware was basic but
functional but the software
was primitive beyond belief. Given that the MRC500
had really good
hardware and software (within what was possible in
1897) Zeiss had to
move fast to get into the market - and of course they
did just that.

Hi Everyone,
I didn't get it all right...Here are further notes by Colin --------------------------------------------------------------------------------------------- Dear Shalin, almost correct! Actually wedeveloped the Oxford confocal in 1975 but Oxford Opto wasn't started till 1982, with SOM25. In 1984 rights were assigned to Dubilier. They introduced the name Lasersharp. In 1986 rights were transferred to BioRad, who bought the Lasersharp factory in Abingdon. Polaron was a subsidiary of BioRad in UK. With regard to papers on confocal fluorescence there was Ingemar Cox, JMicrosc 1983? Then Brakenhoff and van Resandt. Latter started Heidelberg instruments who also launched early confocal 1985? This was later taken over by Leica. Another paper was Carlsson optics letters 1985? Colin On Nov 8, 2007 4:26 PM, Guy Cox <[hidden email]> wrote:

A clear distinction should be made also between stage-scanning and beam-scanning. In this respect which was the fisrt beam-scanner? Concerning Sarastro, since I am now located in Sweden I contacted Kjell Carlsson couldn't recall. Niels Alsund, then president of Sarastro, says that the commercial company was founded in 1986 and sold its first set up the same year here at the Karolinska Institutet. The prototype however was running before that (probably at KTH where Kjell worked?) but I got no dates on that! Best Whishes to all.
