Hello,
We are having some problems with our Zeiss LSM 510
META argon laser (488 et al). Basically it's getting old and due a replacement,
it's no longer producing the power it should and we're also getting frequent
error messages:
Object: COM3
Read time out Object: COM3 Read time out Object: AOTF Driver IsHwAccessible failed which means we need to restart part, or
all, of the system. Zeiss have told us that we should replace the laser and
power-supply and the problem will be resolved. We will be replacing the laser as
soon as possible, but I wondered what the advice from the list is
regards whether or not we need to replace the power-supply too? It adds quite a
lot to the price. So, from your experiences, should the power-supply be replaced
at the same time as the laser? If we don't could our communication problems
persist?
Thanks in advance for your
help.
Graham

http://listserv.acsu.buffalo.edu/cgi-bin/wa?S1=confocal This is just a general comment about the laser power supply electronics. To keep sizes small, modern power supply components are worked fairly hard; most use switchmode power conversion technology and the capacitors run a very high ripple current. All electronics have a lifetime that is dependent on the conditions of use and these components are probably run at good design parameters but still operate at elevated temps and are probably "tired". With aging, the Equivalent Series Resistance of the capcitors increases and the ripple voltage increases. What I am saying then is that it may operate the laser if you keep the old one, but the performance is likely dropping off or may do so in the near future. From the company perspective it is more likely to give good performance and happy customers if they are cycled at the same time. I can't comment on the error messages. I would trust Zeiss since they know these messages. Our Zeiss service has been very good with getting the correct parts first time based on the system messages and symptoms. I have no association with any commercial interests.

I'd try to have it refurbished; we just did that with an old, non-functional Ar laser, including an overhaul of the power supply, replacement of the laser tube, and increase of power output, for significantly less than the price of a new one. The work was done by Dynamic Laser in Salt Lake City, Utah. No commercial interest of course, just a happy customer. Let me know if you'd like further details.

http://listserv.acsu.buffalo.edu/cgi-bin/wa?S1=confocal In the past we had some laser replacements without power supply or replaced power supply without laser and it often tuned out that we needed a second replacement a few weeks later. Nowadays the laser and power supply are replaced together leading to less down time and less service visits. The error message doesn't seem to indicate a problem with the laser, but with your AOTF. Good luck, Gert van Cappellen Graham Wright schreef: > Search the CONFOCAL archive at > http://listserv.acsu.buffalo.edu/cgi-bin/wa?S1=confocal > Hello, > We are having some problems with our Zeiss LSM 510 META argon laser > (488 et al).

http://listserv.acsu.buffalo.edu/cgi-bin/wa?S1=confocal Hello, the error message about the COM port is not related to the Argon laser head or the laser power supply. It seems more a problem with the AOTF driver in the system. We ll get in contact with our Service team in Singapore to solve the problem immidiately.
