Hey

 

I'm working on some very small sculptures. I'll attach an image of a working sample (the figure in the image is about 0,3mm wide).

 

The sculptures are going to be exhibited relatively soon. But I'm having some technical trouble with how to actually show them. You need a magnification of about 20-30x to be able to view them properly. I have some loupes that do this; however, their focal length is only about 10mm and I want a larger distance to the object. Ideally 50mm or more. This is because I also want people to be able to see the sculptures without magnification (to better understand their actual size), so I don't want the loupes getting too much in the way of the normal view.

 

I'm attaching a sketch of how I would ideally like to exhibit the sculptures. That is, in glass vitrines with built-in magnification of some sort and a relatively large distance to the object. And if possible, with the means of magnification looking very simple. Does anyone here have any suggestions?

 

I've tried a number of different things. What works best so far is a home made microscope where I attached two lenses from single-use cameras to a 165mm tube (using this guide: http://www.scienceinschool.org…..microscope). It gets about 20x magnification and a slightly larger distanDSC_0027_red2.jpgScan-3_red_tekst_eng.jpgce to the object (about 35mm). However, the image quality is very poor. Can anyone here think of a way to improve it? I'm guessing better lenses would go a long way, but I really don't know much about lenses.

 

I would be grateful if someone could help me out! – Laurits

HELLO:

I your sculpture at 3mm and drawing  present a challenge.

I do not know your timeline, there are a couple devices I could suggest on Ebay.

One is a portable microscope with a focusing range of 3-40mm at minimal cost.

or you could go hi-tech and use a cheap digital point and shoot camera.

The two image were taken with a P&S camera at 50mm and 40mm.

You present a challenge that really requires a bit more thought and experimentation.

Hi Laurits,

I would suggest you use a stereo microscope, these can give the magnification, working distance, and resolution you require.

Good luck.

Peter.

Hello Laurits,

I'm amazed that you can work on such microscopic sculptures!  Only part of your image and drawing are visible– could you prehaps reduce the width to no more than 800 pixels so the whole thing can be shown?  Are the sculptures displayed along a straight line?  If so, one possibility is to use Peter's suggestions and have the stereo microscope move along some kind of optical bench or rails, so it can only move parallel to the sculptures.
