Diode mounting block group buy.

[dave]

Another group buy, but this one intended to be modular to suit most TEC applications, and especially suited to combining diodes. They address the shortfalls of the press fit style diode holders, and have integral M3 mounting holes drilled and tapped in the base.

Feature screw on retainer to lock the diode in place, and also a screw on base plate.. The base plate can be orientated with either the mounting slots at front/back, or left/right

Threaded m9, 0.5 to suit aixiz, or any of the other lenses that utilize that thread type.

Price per set of 3 brass parts will be $25USD for singles, and $20USD ea for 5 or more I have 100 coming at this stage..

Any interest?

What is the beam height?


-Brooks

[dave]

Beam height is 15mm without the bottom mounting plate, or 19mm with the mounting plate.

Seems like a decent design. I might be interrested in two.

[mpoulton]

This is great - I was just working on a design almost identical. However, brass is very poor for thermal conductivity. Have you considered making them out of aluminum? It has about 2.5X the thermal conductivity and is still easy to machine. Cheaper, too.

[dave]

Brass still has a OK thermal conductivity, and its really not a issue with a tec sitting right underneath it.

The reason as to why I chose brass is it has lower heat expansion properties than aluminium, so the collimator lens should in theory remain more stable...

6 of 1, half a dozen of the other..

The delta-T between the laser die and the bottom of the mount may be surprising. 6W is a good bit of power, and there are four thermal interfaces in there too (die to can, can to mount, mount to base, base to TEC).

What is the center-to-center spacing of the lasers when stacked side by side?

If I understand correctly, you run the TEC a little harder to compensate.

14mm

[edison]

All the profesional companies use brass mounts to hold their diodes so i would definitively go for brass.

looks good dave

[p1t8ull]

Very nice design, please put me down for a couple for now

[loopee]

Hey Dave

Could be interested in a couple

Are you including the screws in the price or just the brass components?


Troy

[dave]

I think I can include screws, for sure.

[badger1666]

two for me please

[danielbriggs]

Can you post the dimensions of the unit?

Ta,
Dan

[uk-laser]

Hi Dave,

Excellent little design.
Put me down for 5 pieces please.

Cheers,
Robin

** edit ** sorry - ended up needing them in a hurry so purchased some alternative mounts. 5 pieces no longer required. BRs, Robin

[Law99]

Hi Dave,

Nice looking design! What would shipping be to the UK for lets say 5 and 10 units please? Thanks!

[djlorenz]

mmm... maybe interested in 2x... how the tec cooling works?

[mophead]

maybe up for 5. maybe 10 depending on the outcome of the 640 diodes.

[dave]

Hey Dan,

IIRC ( Im not in front of the computer ATM ) the mounting block is 16mm deep x 14.9mm across x 22mm high. The mounting plate is 4mm high and the slots are on 25mm centers.

Can you post the dimensions of the unit?

Ta,
Dan

[dave]

Airmail will be the way to go. I think I can get these in a letter, so the shipping shouldnt be too much at all.. Guessing around $10-20 for 10 pieces.

Hello!

I am not trying to be dense, but..

Can you explain this a little more?
Here is what I gather:

The diodes fit in the back, and the plate holds them in tight,
then the standard axis lens can screw into the front.

is this correct? If so, I love the design, and will want some

[aijii]

Yep you got it.

Diode orientation is easy to adjust at any time by loosening the plate.

[mpoulton]

I'm in for 10, then. Looks good and saves me some work!

[dave]

Looks like there is some interest!

What I'm thinking is Ill hold off on taking money till the parts are nearly here. Probably looking at a couple of weeks

[Doc]

I'll take 5 Dave.
