Microphotography vol. 2: Mitsubishi 660nm Red laser diode

[crazyspaz]

I suggest trying these. Super cheap, easy to power, fairly hardy, and-best of all- the lens pops off, so you can get pics right up on the exposed die.

Smeerworst: :thanks: for the comment. I still remember some of your macro pics somewhere on the forum, found them inspiring among others before making my 1st microphotography session of the 532nm module:beer:.

crazyspaz: cheers for the link! How could I missed that:thinking:. Fasttech was rather a flashlight source to me mostly, but this looks plain simple and ideal for the macro job. In the meantime I have another member's possible simple set-up waiting for me, so will see.

WOW! Those are some really nice shots! All my super macro shots have extremely terrible DOF -- assuming I can even get the subject where I want it in the first place.

Amazing photography skills... You are very good with a camera!!:bowdown:

+1

Blord has competition

+5 For the amazing photo's. As Larry said, pics with the laser Lasing would be brilliant, Blord did it and it set the bar a little higher .

Great work.

I'm putting something together so that we can have some lasing macros.

Bionic-Badger: I value your comment, sir. It's mainly about having access to the right equipment. The one I've used isn't that fancy at all, the actual microscope used is Kolleg SHB45, which is a basic type that can't compete with more modern magnifying devices. Still it served me well for the purpose.

Polonium210: thank you. I can see from your signature your photography skills aren't the worst either:beer:.

ped: appreciate the rep and support. Blord's done a tremendous macro work on some of the popular diodes, I believe it was piferal who was more active when it comes to a lasing diode under the microscope (not to mention the handy measurement scale provided in the pictures).

WBS: Looking forward to it already!

Allow me to add 6 more pictures of the DSLR mini set-up used for the microscope attachment. It consists of the actual glass adapter, which "simulates" the normal lens which is attached to DSLR body normally (and replaces the original microscope eye-piece on the left or right side of the tube compartment) and the so-called T2 ring for Nikon fit. Both parts are made of a good and sturdy alumiunium, screw in smoothly and perform nicely. Here's the link where I bought this handy equipment, seller offers fitting for Canon, too:

T2 ring.

Together before assembly.

T2 ring screwed onto the adapter/assembled.

Of course I meant Piferal

Stunning photos Gismo. I can't imagine the knowledge, skill, and patience it takes to create them. Thank you for sharing.

Please excuse my dumbassery. Where it the point that the photons are emitted from the subject emitter? Is it from the end of the black thing that is on top of the black speckly thing in this picture from the above OP?

Fantastic photographic work. Truly outstanding and of great interest to all of us here on LPF.
Being able to see such detail in such clarity is remarkable. Seeing these photos take some
(some) of the mystery out of these little marvels of optical magic. Thanks you very very
much for sharing them with us all. First class photography!!!!!

ImA4Wheelr: :thanks: for the comment. To give you an idea, after googling a bit, you can have a look at a very interesting pic right here:

Laser diode under microscope : Svarichevsky Mikhail.

Very nice shot, if you ask me! Something I'd like to see on my own. Although not sure if that one is a representative sample, you definitely check out some of the piferal's magnificent macro-lasing-diode-photography!

COMMANDR: thanks a lot for the support:beer:.

 

[piferal]

Hi gismo.

Congratulations for your work, very nice pictures :beer:

And I fully understand all the problems you may have to perform this type of photography for having experienced these first hand, plus the time that this type of photography requires.

Keep it up.

Cheers.

piferal: words of encouragement from you, sir, mean a lot to me, so they do! Much inspired by some of your high-tech macro photography I've started this adventuresome journey. I'll see what else can I contribute with in the coming future. But it'd be certainly great to see you back with some more photography goodness as well, if you get a chance:beer:.

I am sure you that with the passage of time and with the accumulated experiance, plus the suitable material his work will be even better
because you has very good attitude.

Now you know it is a time consuming job that requires a lot of patience and a some skill, and plus is not an easy work because you have a lot of
optical limitations at this scale, for so, I value your work, of course :beer:

Although for me the worst part of all this is the price of materials, because if you want to have a certain quality level of tools that facilitate and
give you more easily the quality of his work, is not cheep.

Just saying for those who are not aware that a decent microscope objective that allows you to work at an acceptable distance, (known as LWD,
SLWD and ELWD objectives) with good optical quality, are expensive and not so easy to get , for example a good quality 20x and with good working
distance can easily cost over $400 (second hand, of course), and that's only one part of the necessary material.

I can tell you, I don't even have a microscope!! lol, because I have no budget to devote to this area , just a couple of mediocre and cheap objectives,
one average photographic camera, plus other things like rails, micrometers, stand, lighting, and others, based only on my DIY.

By this I mean, of course, I'll take more pictures of laser diodes, but I need a little time and dedication to get something pretty good with the material
that I have, of course for me is not even nearly the quality I'd like to have, but, I make that I can with what I have, lol.

Keep your nice work up, and if you need anything, just ask, I'll be happy to help you.

Regards.

Pd. Sorry I can't rep you for now.

Thank you Gismo for googling that info on my behalf. Very generous and kind of you. I feel very humbled. The 2 pictures in that link are incredible.

So the photons are emitting from that thin copper colored line that is between the 2 objects I referenced in the question. Makes me appreciate you pictures even more as I didn't notice that detail when I looked at your pictures prior to knowing that.

Thank you again. :bowdown:

Really revealing macro shots! Good job gismo! Diode junction/emitter and gold bond wires for all to see. An interesting failure mode close up. Golds melting point being 1947.52° F/1064.18° C

If only the bond wires could be tungsten.
