Hi there,

I need to photograph small objects at a distance of 2-4 inches (5-10 cm)
from
the lens. I want a magnification of ~50 to 100.

If it can be done, then the people at Brunel Microscopes will know:

I have several of their IMXZ 'scopes with digital cameras for field of views
ranging from 50mm diameter down to around 1mm. At 1mm you will easily be
able to count/detect 50um particles.
