Thanks. I'd thought that low modulus silicone (uses alcohol instead of acetic acid) would be better, but in this case the acid is an advantage. Got to wonder about cleaning for reuse, but in that case the optic mount should go with, anyway. I'll pass on the epoxy. Too rigid, and weirdly elastic though it is, silicone seems to have better long term stability of position than Araldite or similar epoxy. It's nice to know that something doesn't need exotic shortwave light cures.
I've been thinking about real-world testing of the dichros' performance. I've got a Spectra Physics Millennia Xs in the lab right now. It makes 10W 532nm in a 2.3mm beam which is reasonably high power density. I can also set up a 6W 480nm Taipan laser and test light blue T/R. I should be able to test with these lasers in the next few days. Deep blue and red may have to wait until I have the new Brightlight laser projector here.
If anyone is seriously interested, I could also test with a 577nm yellow Taipan. From the graphs, it's clear that Dichro A will not work at 45 degrees, but I can see if it works acceptably at a shallower angle.
Any reason to test these at 405nm? Didn't think so
Brad,
A couple of ideas here. I would use only one of the dichroics to add the red at the end and leave what you have for the green and blue. This way you gain 1/2 of the potential benefit for almost no effort. You might look at getting a power meter. Your range of 10-100 mW is 1-10% for a single color in that projector. That is very good to very bad performance for a dichroic. A good power meter is invaluable for fine tuning these projectors and comparing improvements. I'm sure there are many on the forum that can suggest or even supply some different turn key systems from cheap to pricy.
Junk,
What I would like to know is how high a power density is too high and is the reflected beam measurably distorted? I don't think there will be much interest in 405nm or 577nm.
Very impressive results so far.
My only question Bridge is are you going to be doing any other coating combinations?
Kvant do combined Red & Blue modules: http://www.synchrovision.co.uk/637nm...al-r-b-modules and these are fitted as standard in many of their off the shelf projectors. I don't think they're alone in this.
So to cater for these a pass Red + Blue, reflect green coating is required and a dichro that's the inverse of that (or broadband mirror of similar reflectivity ie. reflect red & blue).
ok so when can we get these?
I have a Scientech 365 although, I don't fully trust the results. Imagelight and I did dome measuring on that projector recently with his power meter and I just simply can't recall what the loss was. It was more than I would like but, I also recall being surprised it wasn't more. It also has a dichro for the green rather than a first surface mirror which made me scratch my head a little.
If the module already combine blue and red, maybe reflect green and pass red and blue is needed.
Question is how many people interesting those dichroic? as you know for coating, more small quantity meaning more expensive.
If we can catch 100pcs or more, with reasonable prices, sure, we can do.
Best regards!
Bridge
