Based on a recommendation in these forums I bought an American Optical 570 stereo microscope on ebay some time back. I added the illumination shown below, I thought it might be useful to others. I cut 3 pieces from a right angle piece of aluminium section, coated them in heatshrink, attached them to the lense with zap straps and then used tiny zap straps to attach LED car headlight rings (80mm, 100mm, 120mm - also from ebay). They're powered through a pwm dimmer as the glare can get too much from very reflective surfaces.

The dimmer works well for flaring. I played with the position a little, in general you're looking at a flat surface with the lens/lights on an angle so most of the reflection is away from the lens.
