Hi KGB, I am going to be needing the same very soon! I believe Laser-Wave sell such dichro's. I will contact them and start stocking them, if possible :)

Cheers,

Thats nothing, you should see it now. Its got the case almost finished and has a few more components added like shutter and fans etc...

Her is a video from when I first got everything together:



I will be adding some pics to the build thread probably thursday as its my next day off of work.

o man, that shipping was a killer, like over $120. WAYY more than I expected.

Stay tuned B/C that laser went to a very special person who has some big plans for it. hehehe:eg::eg::eg::eg::eg::eg:

...and start saving cause this sh!t is expensive. I have slowly been gathering parts when I can afford them and building as I have time, and it takes awhile but you will LOVE the end result....and now you don't even need expensive 473 to get a RGB, Just use 445 :)

probably thorlabs, but i don't know their prices .....

Also, is possible that you need to change the disposition of your lasers in the chain ..... is always more easy (and probably more cheap to find) make dichros with a step cutoff, that with a band cutoff ..... i mean, is more easy that you find something that pass anything over 500nm and reflect anything under 500, than to find one that pass anything, except 440/460nm ..... so, you probably need to change the lasers in the chain for get red-green-blue-BR, instead that add the blue at the end of the chain (or place a FS mirror and reflect the blue in the middle of the chain, and add the extra dichro there, if you can)

445 is better, anyways, as it's closer to the eye's peak blue detection. 473 only looks brighter to the eye because it also stimulates the greens. You can get the same effect and color by simply turning the green up a tiny bit in your scanner, and then your "473 color blue" will be even brighter than if you instead had a 473 in there at the same power as the 445.
