G'day,

going to be purchasing a microscope soon, what magnification should i go for to see the like this:

as seen here: [I]http://laserpointerforums.com/f65/dave-mean-his-diodes-445-macros-image-heavy-54033.htm[/I]l

Cheers!
 





I'm gessing 30-50x?

im not sure though

have you ever looked at spyrogyra though a microscope?

Looks pretty cool :D
 
Woops, its spelt: spirogyra :D

these pictures dont do any justice... they look much cooler in real life...

not 100% sure, But, I think they are the cells that make up plants...

Sorry for the large pics. If anyone is having trouble seeing them, tell me and I will resize em...

Wow cool they kinda of look like tiny backbones. And that picture of the diode...it looks like a dead one you can see at the juction that it looks like an arc took place there.
 
At super high magnifications it becomes a real pain to light up the surface properly. That said, one of those 200x camera microscopes from Deal Extreme worked REALLY nicely--when the drivers worked.

Im after one with some decent zoom, stereo optics, LED lightinig and camera capabilities.

currently looking at these:

40X-2000X Lab Research Compound Microscope + 5MP Camera (eBay item 400227423252 end time 13-Jul-11 03:28:19 AEST) : Business Industrial

or this:
BARSKA 5MP Digital Microscope w 3.5 Inch Screen RRP$799 (eBay item 190459049525 end time 18-Jul-11 15:04:07 AEST) : Industrial
Click to expand...

2000X is not possible :eek: maybe it refers to the magnification of the objective (which can be up to 100X) multiplied by the magnification of the eyepiece (10 or 20X)...but If it does, then 40X is strange :rolleyes:
 
^I'm sure it's quoting total magnification of the whole system, whatever that means.

Quoting magnifications gets really tricky anytime you're incorporating a camera into the system, and then a subsequent display device.

The quoted ???x number could well be the magnification at the eyepiece, or the magnification at the camera's senser. I'm looking at these photos on a 14.1-inch monitor, which yields some ???x value of magnification. Hook my laptop up to a wall projector and the ???x magnification number goes up even more. Hook it up to a movie theatre projector, and the magnification is getting quite large.

So it's a tricky business to discus ???x magnification numbers when talking about digital imaging systems. That's why it's a good idea to put a scale bar in your image, since the ???x number changes with any given monitor size. Whoever took those pictures in the OP must've just been some lazy idiot to forget such things. :tsk: :whistle:

(although in my defense, I did measure the actual dimensions in the relevant images, even if I didn't add scale bars in all of them).
 
Series of images of the same subject, we can infer the dimensions. PBD, still have my vote for best diode macros ever.
 
I took all these with a AO microscope that has a variable zoom of .7 to 4.2 and eye pieces that are 15x, so the resulting magnification can be from 10.5 to 63x.

this is a GGW 6x diode


some other diode I don't remember now.


This one is a 445 and has burned bond wires.


This is an LOC red.


This is an LPC-815 IR diode.

Same diode at higher power.


and a 9mm IR diode.






it looks like there is a light on inside, this is because of the good illuminater that came with this microscope ;)


Yes microscopes are fun they can take you to a whole different world that is for sure, they can also be expensive for this one costs $1200 when it was new because of it's superior optics.
Who ever says this hobbie is cheap doesn't really know what they are talking about :crackup:

Pretty good macros I think considering i made the rig in like 3mins from stuff laying on the work desk.
 
Well, still a work in progress. The third picture i just took about two hours ago, the first two were taken the day before yesterday. Also not solder per se, but yes.
