Pictures of decanned 445nm diode.

I tried it with a tiny piece of glass fiber optic.. This is the best I could come up with
even though the center is hollow.

It did have an affect on the beam but need to play with the idea more. That piece
is epoxied in place, but it is much more difficult to find the right position. Comparing
the position to a c-mount for example, there is nothing to rest it on. The point of
emission is in a very awkward spot and getting it to sit just right is nearly impossible.

I got it close, and could not even guess how much it is off the center line, the beam
on that LD exits slightly crooked..

It appears to help the shape, but doesnt appear to help divergence. If I take another
stab at it, will definitely post some pics.

Im getting anxious just looking at that pic, mind boggling how small this is without
the magnification :drunk:

I actually have some FAC lens that you could have for your experiments. I got them from the Hurc auction, not sure what to do with them.
I'll see if I can find them and how many I have....;)
 





Supper pics !
Educating ! And supper control of the dremmel !
It's like using a bulldozer for tootpick
Now I know why u told me last year I am going to concentrate me on photography
Now this is raely concentrated
Supper pics !

Sounds interesting... I had one, but it went flying while trying to remove
it from a cmount..

I must have spent a good 4 hours looking for it, but its comparable to finding
a needle in the Atlantic :cryyy:

I have to make a special mount and try again.. Positioning these on a cmount
is pretty easy, but on the 445's there is no level ridge or any platform to hold to.

With the surface tension of the epoxy, you have to wait till the glue is near cured
then attempt to mount the lens. The window to do this is very short, and just adds
to the difficulty of getting it seated just right.

Good thing I have several inches of the fiber op, its inexpensive to practice with.
Time consuming none the less.

well continue practicing with the fiber, i'll see if I can find the FAC's and some way to package a couple up to you. No promises, but if they are there i'll send them to you. I don't think that I will get to that anytime soon.
 
Definitely :D Appreciate the offer :beer:

If you end up trying this, I found another picture which shows the front.
I had to make 2 insanely small posts out of epoxy on the c-block then
place the lens as close to center of the top of the chip.

This one was ever so slightly too high which bends the light down and
when collimated the beam exits in the same direction..
One of the hardest things ive tried yet, and was close but no cigar :undecided:

Well Damm!! I have to say that's pretty good placement without, from what I understand, a lot of very expensive equipment.....LONG LIVE DIY!!!! very impressive!
I'll look through tomorrow and try to get them out to you if I find them.
 
Nice macros! :) How much did that macro lens cost you if you don't mind me asking?

Heres one of mine :)

These pics are awesome! I have a 100mm macro lens too with my canon 5d mk1

Can you explain the part with the inverted 50mm lens?
 
The Canon EF 100mm macro can get to 1:1 magnification. This means the object in front of the lens will get the same size on the CMOS imagechip. In order to get beyond 1:1 you can do several methodes :

1] Buy a better macro lens like the Canon MP-E 65mm f/2.8
2] Use a close-up lens.
3] Use extension tubes.

I am using methode 2. Mount a 50mm lens reverse in front of the 100mm macro lens. You need a coupler between the two lenses. Here you can see how the setup is, Reverse 50mm Macro Trick – The Setup | Tyler Ingram Dot Com
The results are very satisfiying.
