We are a factory of miniatures. We want to scan our miniatures (2cm maximum in height) with details of 4,5 milimeters.
I read about assemble a macro in my projector and a zoom lens in my camera.
We work with the equipment that comes david scan.
What do you think about this? Anyone prove it? Do you have any solution?
Thank you for all!

There is an example of the extreme micro scanning in the old DAVID forum, you can take a look here:
Hope this helps.

I don´t know what is the model of the david SlS2 camera. Can you told me the exact model of your Fujinon lenses?
Im going to buy this too for my projector.
I see that I can installing a second camera in my scan. What do you think about it? Can we have better results?

I am in a similar situation, I am looking to image some invertebrates for taxonomy (the cool newish field of cybertaxonomy).
I have the DAVIDS SLS system (DAVID 5), two cameras (David Cam 3 & 4, same lenses), ACER projector and turntable. I am using a DELL laptop (Core i7-6700HQ@ 2.6Ghz, 16gb ram, NVIDIA GeForce GTX 960M).
The dual camera system does not work very well – the DAVID Cam 3 does not have the resolution of the DAVID Cam 4.
My intended cheap-ass workaround:
- Discard the kit cameras/lenses and use a Canon DSLR with Macro lens to increase resolution (better sensor & optics). I have tried this already as I had access to the camera and lens. However, the DAVIDS software is not recognising the DSLR so I am using third party software, SPARKOCAM. This is not ideal as it negates the sensor qualities of the DSLR but still allows me to use the better optics. An alternative would be to buy a better industrial camera with extension tubes/better c-mount lenses (costs money, which as a poverty-stricken taxonomist I do not have), advice would be helpful here.
- Print out new calibration panel (15mm scale). Any advice on how to do this?
- Diopter in front of projector lens (have yet to do this, advice on brands, types etc). Advice here as well please. If a better projector is the key, then can I get suggestions.
- A big issue I have is with glare, I am thinking of attaching a polarising filter (Cokin)to the macro lens.
I should have some results over the next few weeks, but if anybody has advice or has solved some of these issues then help is greatly appreciated (no need to reinvent the wheel).
