My Setup
Hi,
here are some pictures of the setup I used to make these pictures: http://www.photomacrography.net/forum/v ... php?t=9239
Cheers,
Marc

An elegant and sophisticated setup, to say the least!
Your results speak for themselves, but I'm curious to know how it feels to adjust an SM-25 actuator with a 2 µm increment.
Here is my thinking... The SM-25 is described as having a vernier reading of 1 µm, but the screw pitch is 0.5 mm. 2 µm is only 1/250 of a full turn, and the scale diameter appears to be only 1.5 cm or so. Contrast this with an Olympus CH microscope focus block, where 2 µm is 1/100 turn and the scale diameter is 5 cm. On the surface, it seems like the focus block should be "over 8 times easier to set!" (written as advertising hype for amusement).
But I have not had hands-on an SM-25, so I don't know what it feels like.
What are your thoughts?

Andrew, I drilled holes using a drill stand and inserted metal dowles for the screws.
Rik, moving the stage in steps of 1µm is a really hard job. But 2µm will be possible if you have a steady hand. What you say about the microscope block sounds much more convenient. I already started thinking about a motorized stage which is capable of much smaller increments

Thanks for posting the photos of your rig.
It is aesthetically very appealing and these rig photographs were very well done.
The blue colored parts of the Novoflex components really blend in nicely with the rest of the rig's colors. To my eyes, it creates a nice, high-tech, high-precision look that I personally enjoy. It's always nice when the appearance of one's equipment is enjoyable.
I very much look forward to seeing more of your photos!

Marc, beautiful setup and documentation!
Am I missing something, or does it appear that you are impossibly shooting through the vertical post that holds the subject stage? Surely you're turning the subject stage around to the camera side of the vertical post, right?
Cheers, and thanks much for sharing.

Thanks for your comments.
If I can spend six hours to photograph a bug's eye, I can easily spend one little hour to shoot my rig. I just noticed that I did not very well. My living room table is visible at the lower right corner on the first image.
Chris, I have to admit that this might not be clearly visible. When you look at the second photo you will find the post behind the camera. The camera is mounted in the middle of the marble block and the post is mounted at the edge. This is visible on the third photo where the specimen pin is roughly in the line of the optical axis of the camera.Am I missing something, or does it appear that you are impossibly shooting through the vertical post that holds the subject stage?
Just a tripod an two diffused flashesOk now show us the rig used to take THESE photos. Very cool.

In the third image, see component 7, the "Thorlabs dovetail translation stage DT12XZ/M". This component consists of two linear slides mounted at right angles. The lowest silver-colored handle controls the vertical axis (Y, in marc's notation), while the upper silver-colored handle (between the labels 7 and 8 ) controls the horizontal X-axis. The manufacturer describes this part as an XZ Dovetail Translation Stage and shows it in a different orientation with a different labeling of the axes.One question: how do you get fine adjustment of the vertical axis?
