Hi again, Chris, Do you have a Labophot 2 stage carrier with or without stage? I've just now replied to Pau via PM and email. I think the focus block shown is from the earlier Labophot era, rather than Labophot 2. But I do have carriers to fit either (they are different), and will send Pau whatever...

Was there severe damage to the box?

If not, I hope you are planning to force a return. This is egregious.

I wonder why your object wiggle? I can think of two reasons: external vibrations or mixing currents. For small enough subjects, don't forget about Brownian motion. I've seen serious research efforts attempting to hold small particles, within aqueous suspension, in one place against the random "kick...

Ryan, The main failure mode I've seen in "bad" Mitutoyo objectives is that they are significantly unsharp. This can be caused by bumping the objective in a way that leaves no mark, but irreparably changes the alignment of some optical element(s). I would expect that somewhere between a third and two...

Vauratus, welcome to posting! :D And warning--long answer ahead. Having tested a fair number of Mitutoyo objectives, I don't see anything immediately alarming in the results you've posted. (This said, I'm wary of giving a lens a thumbs-up without a direct, side-by-side comparison.) When Mitutoyo len...

Lothar, this is a very useful post! I've often wondered just what was inside a Raynox DCR-150, and how to take one apart and mount its elements within a lens tube that has more general use. Thanks for doing the fundamental work. :D (I've long wanted--but can't quite justify--a metal lathe. If I'd bo...

That sounds even better! Do you use a special target or "just" text? Just text, but here are some things I've picked up through trial and error: In Microsoft Word, it's possible to enter a very small font size. For some fonts, this number can be much smaller than the lowest number listed in the dro...

Ray, I'll email you on the Lab-2 condenser and the AIS Nikkon 200mm lens.

--Chris S.

But it's still great to check for sharpness and aberrations, especially since I don't have any silicon wafers to test with ;-) I do have silicon wafers, but at low magnifications such as 5x, I prefer to test on laser-printed paper glued onto a microscope slide. I illuminate the paper frontally with...

The question in this thread is about a two-axis goniometer.

Alan, the item you referenced doesn't appear to include any goniometer at all. I don't think it is on topic for this thread.

--Chris S.

Lothar,

I have a Mitutoyo nosepiece that I intended to integrate into my rig, but never did. If this might work for your project, feel free to email me.

--Chris S.

Alan,

At that link, I see translation on the x and y axes and rotation around the Z axis, but no other rotational axes.Given that the question here is specifically about these rotational axes, that stage doesn't look to address the need.

What am I missing?

--Chris S.

Habusho, You might have a look at goniometers from Thorlabs . I use a Thorlabs GNL20 goniometer pair (which is the same thing as a Thorlabs GNL18 lower goniometer plus a GNL10 upper goniometer), and am very happy with it. You can see this goniometer pair in my macro rig: The Bratcam . Note that Thor...

. . .There are different zones in a fen, certainly, with different plants in them. Very true. I used to delineate wetlands with a scientist who was eminent in the Great Lakes Basin. Since fen is a highly-protected wetland type under federal regulations (and also interesting to us), we were particul...

Some years ago, I contacted Nikon Small World and showed them the Bratcam . I was told that it was a homemade microscope, that homemade microscopes were definitely eligible, and that contest organizers were excited to have more participation from homemade microscopes. (Or words to that effect.) In t...
