It looks pretty good, Bernd. I hope it works out for you the way you are expecting it to. I'll be interested in any updates you might have to this.
That is a good question Paul, i will test out the difference. I think it depends on the quality of the used laser.I have some IR filters in my stock from several years ago. I did use them for awhile in some of my builds, but since the amount of IR is so small in comparison to the main 532nm line, I quit using them and they are still in my stock. IIRC, they had a transmission of >98% for 532nm and a transmission of 808nm and 1064nm of <1.5%. Is this really necessary for your Raman spectroscopy or is it there as a precaution?
