What the heck is this for module

It is my old casio diode.
It got a module around it(i think thats how its called) but its 10.58mm in diameter(not measuring the tape around it)
The hole in my heatsink allows for maybe 0.5mm more diamater.

as you can see the lens(g2) is screwed inside the module.
The lenses i see on this site:
https://sites.google.com/site/dtrlpf/home/diodes/445-m140-didoes
Are screwed on top of them it seems, and not on the inside.

Also those from DTR are 11.87mm....so unacceptable for my heatsink.

My question is, whats the name of this module...I want to have one with a M140 in it and purchase it.

thank you so much Dave!
i hope he can sell one with a M140 diode already in.

Will is just selling A series diodes last I talked to him and the refurbed arrays at that. If you hit up jayrob he should be able to make a module for you. He used to make me copper modules fit for the meridith so I am sure he could do this one for you.:beer:

Here are your images for easier viewing.;)

Looks like the module is also wrapped with tape to size it for fitting your heatsink.

A custom sized module can be made, but having the heatsink 'in hand' would be best for sizing the new module...

How would tape help it. Wouldn't that insulate it and defeat the purpose of even having a heatsink?

its heat conductive tape. with the tape it fits 95-99% perfectly.
i think the tape works at least a bit because it puts out 680mW and keeps it stable. and its a old casio diode(unfortunatly forgot the name)

btw, your avatar is great :D

Looks like it might be special tape, but no, it would not heatsink as well.

It would still need to be solidly held so that you could focus it. So if there is no set screw, then you need something like that if you didn't want a permanent mount with thermal adhesive...

what does focus have to do with it? It contains the focussing G2 lens on the inside?
there's a screw on top of the heatsink to put the module tight so it cant move.
The lens is however indeed a bit loose.
When i move the projector and bump it on the ground like 2 or 3 times the lens is already loose and that makes the beam ugly.
But then again thats another problem, i cant see that focussing has something to do with the tape and that it doesnt fit so good.

Jay said "**IF** there was no set screw"

If there was no set screw, the module would spin when you tried to focus it

Thus, **IF** no set screw, *then* the need for the tape to make it fit tight

Peace,
dave
