The DIC (Differential Interference Contrast) may be used on any ultra coax version (zoom or non-zoom) of the Zoom 6000. The module works with object side NAs ranging from 0.05 to 0.50, with optimum performance in the range from 0.15 to 0.4. Lens attachments, operating in the above range will serve for macro applications. Any infinity corrected objectives designed for incident light will suffice for micro. DIC when used with reflected light can often be interpreted as a true three-dimensional representation of the surface geometry. It provides a clear distinction between raised and lowered regions in the specimen.
