Hi all,
I have now seen suppliers challenging us to tell the difference between their single mode and multimode red beams, and Evil Laser's Kore is a high quality projector utilising multimode red. How would 1.5W 637nm fare vs 2.5W of 638nm in terms of visibility? Picture the scenario at an outdoor festival over the heads of the audience. Assuming both have been built to more or less their full potential of what is optically possible, and the 638nm does not have any spatial filtering. Beam characteristics roughly the same at 1mrad and 5mm x 5mm, perhaps the multimode a bit higher, and obviously with wings.
The dilemma is I have 2x 10W green/blue projectors and am looking for a small amount of red to add to them. I am not looking for a balanced white, just a touch of red to make them more versatile for the smaller shows that require full colour.
Thoughts and opinions all appreciated.
