Default LPF member designed host for slow axis correction and beam expansion

This host is a cooperation of design by ArcticDude, Alaskan (yours truly), RedCowboy, and paul1598419 who contributed to a thread I started in the veterans section to discuss the possibilities for a new host which uses cylinder pairs to correct and expand the beam of a high power NUBM44 laser diode (or others) to reduce divergence.

Tero/ArcticDude ended up having the most input and is the primary designer. However, trinh hong phuoc then took the basic design information provided by the group and came up with the idea of mounting the 20 mm DTR module in the center section, then designed the rest of the host around those ideas, so much of its form was also his creation.

This is the core of the host made to hold a 20 mm DTR module and has a slot for adding up to 6x correction power 12 mm wide cylinder pairs to better match the fast and slow axis output of a NUBM44 high power blue laser diode. This artwork was produced by Tero, AKA ArcticDude and was his concept alone:



Trinh Hong Phuoc photos:

If you want one contact him here: https://laserpointerforums.com/membe...nh-hong-phuoc/



[/url]

The core had to be produced to very fine tolerances and was taken to a CNC machine shop which could do the work for Trinh, they appear to have a rough finish in the photo but in reality are quite smooth.

My photo's:



The above photo shows the core removed from the exterior heat sink and has no wiggle room, fits very well inside the finned tube. I plan on using a very thin layer of Arctic Silver heat sink compound on the DTR module end of the tube to help transfer heat into the finned outer tube. If this affects the optics on the far left, I will need to change that out with indium foil.





Each host was machined to be able to use a Sanwu 3.3 x beam expander and holds 2 X 18650 batteries. Although my intention was to use the host for the NUBM44 6-7 watt 450 nm blue laser diode, it is also suitable for just about any of the multimode laser diodes we use which have a bar shaped beam output, if the proper X factor cylinder lenses are used.

The following photo, below, is the host ArcticDude designed earlier with CAD which was used as the basis of this design, he then came up with the idea of a slotted center section inside a closed finned body which was used instead. I wanted a completely closed host because I don't like to see the light coming out of the body, just the end (Since I paid for the work, I had full decision on that).



This was also Tero's design, very close to the final host:



All of the individuals who contributed to the design of this host are receiving one free, so you will probably see more write ups and photo's from some of them too, three additional members who wanted a copy are also receiving one too, I'm keeping three hosts for myself, so they are all spoken for but if you want one I bet you can get Trinh to make more. Once I get my cylinder pairs in the mail and mount my NUBM44 in it I will post more photo's.

I would like to invite the members who are receiving these hosts to please post your builds in this thread later, I really want to see what you guys do with them and any improvements you might recommend, this is version #1, more to follow after your results.

Chris

Great thread, Chris, I expect that trinh will be getting some new business as our members see these builds coming together.
Please keep us updated on the progress of your NUBM44 as it comes together.

Thanks to all you guys who made this happen!

I posted this in the vet section just now but I will put it here as well, I have had this UV glue open ( cap kept on but seal has been broken ) for over a year IINM so I gave it a quick shake and test, it still works just fine, my flashlight is a 385nm 3W led.

I'm waiting for 20mm modules so I can build it out, as soon as they arrive I no doubt want to get it lasing.

Default Re: LPF member design of a host which uses beam correction cylinder pairs

Make sure your surfaces are clean and it's good to do a test if you have scrap to see how it works, I try to not use too much but I do use enough that I can see glue around the base of my C-lens and not just underneath, but I also try to avoid a big puddle, better that it stays put so I error on the side of a little extra.

---edit---

What I have observed, and I could be educated about this UV glue by any experts, but I have observed that it grabs tight when 1st cured via UV light, then the surface gets a little tacky as it fully cures over a day or more, so I always after setting up and curing my lenses with the adhesive, I then add a drop to the edges of the C-lenses and use the UV light to cure that, that way it's sure to hold tight even as it gets a bit tacky on the outer surface.

You don't have to add the extra drops and it will likely hold without it, it's just what I do.

The CAD design works but as you noted allows light to escape and isn't sleek.
I'm suggesting another approach using two inside diameter threaded cylinders that thread into the main body of the laser and each other. Plus two outside diameter matching threaded lens mounts upon which round cylindrical lenses are set. For accurate lens centering a recessed hole fractionally larger in diameter than these lenses can be machined into each lens mount. Each mount should have two divets 180° apart for screwing. Can you visualize this design?

Default Re: LPF member design of a host which uses beam correction cylinder pairs

Steve, I'd like to better visualize what you are suggesting, I may build a version two later, if you have inclination, it would be great to see a drawing.

Regarding this host, compared to the two hosts Tero had drawn in Cad (above), I didn't do this one that way because I think light coming out of the body of the pointer is distracting and lights up the whole area around me at night, I'd prefer not to be so obvious when doing sky beam shots, or putting spots on clouds. The beam may look bright close up, but get out and away from the pointer a few hundred feet and it fades fast. However, an open side window to the optics and you will be highly visible, if not get too mulch splash in your eyes too. So, I decided I wanted to build the hosts which have no viewing of the internal optics, so I don't plan on building either of those two in the future, only improvements upon these solid closed chamber units, if need be. Will know more when we put diodes and cylinder lenses in them.

Default Re: LPF member design of a host which uses beam correction cylinder pairs

Great to see this thread here. Did you get the rest of the hosts you were waiting for from Trinh, Chris? I have been busy building a new module for an expensive 430nm diode for ZRaffleticket. It is done as of yesterday and all testing done. I'm sure he will post a thread about it once he gets the host from Rich and puts it altogether.

You have been here long enough, Singlemode. But, you need 1000 post before you can ask c0ldshadow for veteran status. Would be a great addition to the vet's sections. Hope you make it soon.

I'm probably going to have one unit working today, minus the cylinder pair for now. All ten hosts have been received, thank you for nice packing.
