http://listserv.acsu.buffalo.edu/cgi-bin/wa?S1=confocal Hi Has anyone got any experience of replacing the filter cubes for a TCS SP2 system? Am quite impressed with what I have heard about Semrock filters and am thinking of getting one for Texas Red as I am not convinced that the triple dichroic I have is letting through enough light.

http://listserv.acsu.buffalo.edu/cgi-bin/wa?S1=confocal Just for clarification, Which filters do you mean? If it is cubes, that would be the non-confocal part? Or the confocal beamsplitter where some systems have the AOBS?

http://listserv.acsu.buffalo.edu/cgi-bin/wa?S1=confocal Steffen I mean the confocal beamsplitter where some systems have the AOBS. Possibly what I have in mind is not really practicable. and perhaps as someone else pointed out the semrock filters may not be suitable for confocal. There is also the software side of the equation as well... Just investigating options.

http://listserv.acsu.buffalo.edu/cgi-bin/wa?S1=confocal Steffen, as far as I heard from Leica, changing the dichroics to hard coated ones is not possible - they are too thick for the standard holder. It probably also introduces a shift due to the thicker material, so the emission beam will go somewhere else. You would need to do it on your own risk, I guess. cheers, Michael Silvester Leigh wrote: > Search the CONFOCAL archive at > http://listserv.acsu.buffalo.edu/cgi-bin/wa?S1=confocal > > Steffen > > I mean the confocal beamsplitter where some systems have the AOBS. > Possibly what I have in mind is not really practicable. and perhaps as > someone else pointed out > the semrock filters may not be suitable for confocal.

Hi Leigh, The beam splitters used by the SP2 don't live in cubes, rather they are mounted in a frame in the scanner. I don't know if they are standard sizes or not, but I personally would not want to disassemble anything in the scanner! In my experience, the challenge with probes like Texas Red is the 543 laser, which is really low power (1.2 mW compared to 20 mW for the 488 line) in addition to being off-peak for Texas Red excitation. If you are not using the 633 laser line for another fluor, try using the DD488/543 instead of the triple dichroic - the TD will block some of the Texas Red emission. I have copies of the transmission curves for the beam splitters and can send them along if you'd like - I've found them useful for figuring things like this out.
