Carbon Composite

Carbon composite

The carbon/carbon composite photomicrograph presented reveals numerous bundles of carbon fibers embedded in graphite. A photograph of this particular specimen was entered in a Polaroid photomicrographic competition and Spike Walker was so impressed with the material that he explored microscopy on the original sample. The objective was an epi plan achromat 4x/0.10 NA (polarizing) coupled to a vertical illuminator (Zeiss epicondenser IIC) operating in differential interference contrast (DIC). The microscope was a Zeiss Ultraphot III with an automatic 35-millimeter photohead. The film was Fujichrome Velvia. (2.5x)
