New Module - REALLY easy to use!

I recently noticed that Susie is selling a new module, and I recently picked up several of them from one of my laser display manufacturers so I figured I would share my opinion on them - here's the link to the ones Susie carries:

The COOL part is that the modules are designed to allow diode installation and/or swapping without the need to press the diodes into the module, as they are held in place by a brass "compression style" retaining ring (see photos below, sorry about all the thermal grease!) AND the actual diode mount doubles as a really beefy heatsink, A-La Kryton... The pics are pretty self-explainatory, the modules are a bit larger than an Aixiz (18mm OD) and have plenty of room in the rear housing (with minor modification) for almost any driver (the ones I have are 12mm ID but the actual "pocket" is only about 11mm deep once the actual heatsink/diode assembly is screwed in fully). Mine were shipped with a brass lens assembly and glass AR coated for 650nm lenses, it looks like O-like ships them with a similar plastic lens assembly, blah blah blah, look at the pics to figure it out!

Another nice touch is that there is a set screw in the rear part of the module designed to provide strain relief on the wires, the screw head is nicely recessed and should be perfect to hold an insulator/spring to use these in a homemade handheld if you want.

The numbered, smaller pics are: 1- Diode installed and held in place by brass retaining ring, 2- front assembly with diode and lens installed, 3 - inside view of the rear module assembly, and 4 - the assembled, complete module.

In my opinion, this is a pretty hip little setup, it makes assembly a complete and total "no-brainer" and prevents diode damage when pressing into the module, is already completely heatsinked, allows FAR more lens adjustment than the Aixiz module, eliminates the issue of a "not-totally-pressed-in-all-the-way" diode, is solid as hell, looks pretty cool, etc etc.

All this for only $8 US - probably less in quantity, you'd have to ask Susie!

So it has wires coming out of the back so you don't need to solder the pins?

No, you still have to solder your wires to the diode (as the top picture shows, the wires solder to the diode pins, then you slip the brass retaining ring over the wires and tighten it down, securinng the diode in the heatsink) ...

I'd imagine with a diode that had long pins you could solder them directly to a driver through the retaining ring and screw the whole thing down, but that would probably be a pain (and wouldn't work with standard BR or LOC diodes as the pins are pretty short) - best to solder short wires to the diode and then to the driver (plenty of room in the back of the module to tuck them - WAY more room than in an aixiz).

nice! I've worked on a few DX modules with this setup and I like it a lot... very easy to use!

lol always amazes me to see how mutch cooling paste the put on the diode

Thanks for the Info. Dale. I'm gonna have to look into those little gems

if the only made a square one instead of a round module

Would this be enough heatsinking for a 20x red diode?

I think it should work thats a pretty fat chunk of aluminum there

I agree with John (in fact, I'm harvesting one today to give it a shot myself) ... The heatsink is 18mm diameter, so that gives you over 12mm of heatsinking all the way around the diode (not to mention the heatsink assembly is also 18mm long and finned) ...

I've run these nonstop for 4-6hrs with a 100mW 630nm diode and they stay cold to the touch, plus a couple of them are mounted inside aluminum boxes (at the shows as part of displays) and are hanging on trussing less than a foot above 600w halogen lights which throw off a LOT of heat - no fail.

NOW all we need is someone to suggest a host that uses an 18mm "pill" and let the building begin!

That's really cool. This is 8 dollars, while an aixiz and a custom heatsink is like 20-30 dollars.

Here's the answer to the round -vs- square issue, this is how SHINP mounts these modules in their laser displays, just a square chunk of aluminum with an 18mm hole drilled through the middle ...

if you have access to a drill press and some patience, should be a pretty easy build - there's a company here in WI called "Speedy Metals" that will precut the aluminum stock for you REALLY cheap (in fact, for around $13 shipped on Ebay they'll sell you 2ft of 1.25x1.25" 6061 stock, and if you call or email them prior to shipping they'll do the cutting for you too at like $0.50 per cut) - then, a quick trip to Home Depot and a drill/tap for $4.75, now you've got your set screws as well as mounting holes wherever you want them.

Better yet, wait 15 minutes or so and I'm sure Jayrob will have mounts available as long as the interest in these modules is there ;D

cool i have to order one

I would really like to see you screw that square nut into that square module.... ;D ;D ;D

Lol, Laserbee. Now what I would actually pay money to see, is someone tapping out a square thread

Looks great, are these only good for reddies, or can we swap out the AR coated lens for something else fit for blu-ray?
