My new stage ...

Post by AndrewC »

I've spent the last several weeks rebuilding my main stage and here it is reborn :)

Image

A few changes:

1) Automated x-axis: previously I had two x-axis drives, I've replaced them with a single Parker-Daedal 402LN with 2mm screw pitch. This gives me 1.3um step resolution which is just fine as the thinnest slice I use is 5um with a 20x objective. The axis is driven by a microcontroller /stepper drive which I'll post another day.

2) Camera / lens mount is now modular: my PB-6 is directly bolted to an Arca-Swiss plate which is clamped with quick release Wimberley A-S clamp mounted on the linear slide

3) Subject mount is my 3-axis goniometer, held by a magnet to a small precision linear slide. This lets me easily pull the subject away from a lens if I want to work on it plus if I was to drive a lens into it the subject mount will slide back.

4) Subject stage is still sitting on Melles-Griot micrometer driven precision stages for y and z axis fine positioning. These are now held by a carbon-fibre laminate onto a 20mm steel "optical post" I made after inspiration from Chris. Gives me coarse z-axis positioning.

5) Flash arms are shown lying down here but are Loc-line sections on mini ballheads normally raised up to subject level.

6) As before, the whole caboodle is bolted to an Alumimum track embedded in Oak sitting on Sorbothane bumpers.

7) Left off here for clarity, but a diffuser cone / tunnel / or whatever is held in place by another loc-line section.

Happy times :)
rgds, Andrew

Very beautiful set up!

Hi Gene,

Thanks :) The aluminium rail is some profile I picked up from a guy I know in Germany who buys trade show samples so he often has odd sizes in interesting profiles. I find that cnc suppliers often have hefty Alu profile.

In cross section this one looks like:

I've no idea what it was originally designed for but it met my needs perfectly :)

:-k I'd have to work out the pricing structure first and, coming from the semiconductor industry, it would probably start out in the millions !!!
