Nathan, they are about 0.5 mm acrossNathan Renfro wrote:Nice photos . This strain birefringence is normal in diamonds. How big are these crystals? Diamonds are one of my favorite minerals to look at. In particular, their surfaces can be quite spectacular using epi DIC microscopy.
This example is a flatter crystal

When I say a Lambda, I really mean a home made phase plate out of plastic. I also rotated the top polarizer slightly as it transitioned from magenta to green and found a more neutral colour and then did white balance in the camera to remove off colour.JL wrote:Given the color of the background, a 1/4 Lambda plate was used. A Lambda plate would produce a bright magenta background-color.
