This is a sample of coarse Palogonite soil from Hawaii. The out of focus areas are too close or too far from the lens to be in focus. The sample is placed on a black anodized aluminum plate. The illumination was by the red, green, and blue LEDs in the optical head. This image is a composition from 3 monochrome images. The individual images are shown in thumbnail below. Clicking on a color name will take you to a full size view. No UV image was taken as the other palogonite samples did not show any fluorescence.
