    I had one of those but I sold it because it was kind of lossy with the pass through of the other lasers. Do you have a meter so you can take readings after you get it?

    If you have a thin spot, you can use "knife edging"

    No meter, but I might be able to borrow one. I'm thinking about putting blue first so there is no pass through issue with other lasers - if that is possible with the dichros I already have in the projector. I am still waiting for some parts to arrive, so it will be awhile before I get the 405nm added.

    I'm not sure if the other dichros will pass 405 or not. ALso that means your 473 (which is the most expensive laser) has to pass through ( and suffer losses) on all the other dichros.

    on the laserwave reflect 405nm pass everything isnt very good.

    i have one and i lose about 100mw of red through it

    That is what I was afraid of and why I thought about putting the blues first in line....but if the other dichros won't pass 405nm I'm screwed.

    There must be a good way to combine 405nm and 473nm and not loose a ton of green and red.

    Hummmmm.....what to do?

    There is but it depends on how much you want to spend. I ran the numbers on my 2W projector setup and buying the semrock dichro saved me as much money as it costs. If you weigh out the cost per mw of the four other lasers running through it.

    I'm sure there may be another option but not one that I know of.

    No, they are "only" $195 plus shipping. http://www.semrock.com/Catalog/Categ...?CategoryID=83

    What is the power of all the lasers you are trying to combine?

    You are right about the price. At first I was thinking I would need to replace all my dichros with those spendy ones. Looking a little more at that site I think I can just add the 405nm blu-ray diode and the LM01-427-25 405nm dichro to the end of the line and still get well over 90% transmission of the other lasers.

    The 405nm will be roughly 400mW and the existing 473nm is 200mW.

    I think this will work perfect. Thank you very much!
