Abstract: A brightfield/darkfield microscope illuminator has two axicon mirrors 30, 34 and a third plane mirror 26 for use with two light beams from different sources.An open shutter 20 positioned in the path of one beam 16 provides brightfield illumination. An open shutter 22 positioned in the path of the other beam 18 provides darkfield illumination. This illuminator easily switches between operation in the darkfield and brightfield modes, uses substantially all the light in one beam for darkfield illumination and easily balances the illumination between the two light sources.
