Just tinkering with something 638nm RED 8W and bright as hell.

Granted, my understanding of pinholes is not that great and I am quite possibly wrong but if I remember correctly, pinholing has to be done at a decent distance away from the collimator or you will lose luminosity

The distance does not matter. What has to happen is for the laser to be focused and it is at the focus is where you need the aperture. Then you re-image the focus to the minimum diameter in the far field. The simplest example is a 1 power telescope with two matched FL positive lenses and the aperture at the beam waist between them. This is necessary because the stray rays that you wish to eliminate in the far field are only completely outside of the beam at that first focus. A round pin hole is also not likely the best shape for these composite beams. After the fact fiber, also will not work. No way.

Now Andy...Andy please stop answering around the questions. You started this and imply this is a super duper solution to red. OK, but this might put a lot of projects on hold while you parse the information. That will be very frustrating and time wasting. If you are trying to limit access to the supplier because you have invested money in this corrected module then state this clearly and as soon as you can provide some pricing and a time frame for availability as well as beam shots that will be helpful. In the meantime, those of us who are interested can begin a search for an alternate source.

Cheers.

Now Planters, Planters chill out, I am not one for taking orders.

Not a bad idea but the heatsink alone is a house brick size; and then it is not so cheap like a handful of 445 diodes. mmmm a portable 8W red, now you have me thinking.

Nice find for projectors but with something that small, why is it I fear 8W laser pointers are on the horizon?

(Not saying Andy will do that but I'm sure certain laser pointer companies might).

Am I missing something here? I did not see Planters giving orders in previous posts, but rather, he was asking for more information. So far you are just sort of taunting everyone, like a child with a new toy that wants everyone to know he has it, but won't share. Innovation comes from collaboration, not isolation.

Innovation comes from collaboration, not isolation..

HAHA, ok, so let's have some constructive input/collaboration from you then.

[Stiffler]

I'm not offering any help, Planters was. I only chimed in because you were starting to sound like a dick.

Andy, that looks like a great find, thanks for sharing with us and I look forward to following this thread. If any become available at anytime for any amount, let me know please. I can live with 8Watts of red with 1x4mm and 2mRad...

Andy,

I'll leave you alone. But. I recall clearly the back and forth when the mitsu lens was being debated and this seems remarkably similar. I'll post when I have something interesting to share.

Hi all,

Have a look at this: http://www.sony.net/Products/SC-HP/c...sideview55.pdf

Cheers.

You should also recall that it was me who discovered the 2mm FL lens for use on the Mitsubishi Diodes, info given for free to other to make money selling.

I don't think I need to say more.
